THE MORE IMPORTANT RECORLS FOR JANUARY AND FEBRUARY, 1933 
The winter for the most part has not "been abnormally severe on most insects. 

The grasshopper situation is much less alarming in the western States than it 
was a year ago. North Dakota alone shows an increase in the number of eggs now in 
the ground over the number at this time in 1932. 

Unusual numbers of white grabs are recorded in the Middle Atlantic States from 
Pennsylvania to Virginia, and also in Iowa, and will probably be destructively 
abundant in the latter State, where Brood A is due to appear this year. 

Chinch bugs appear to have wintered' successfully throughout the greater part 
of Illinois, westward through Missorui into Kansas and Oklahoma. The insect is 
also recorded in threatening numbers in isolated localities in Iowa. 

Abundance of fruit aphids is reported from the New England States southwari 
to Virginia as subnormal. A similar condition also prevails throughout the East 
Central and West Central States, 

Citrus aphids appeared late in February in considerable numbers on. young 
citrus trees in Florida. 

The vegetable weevil did damage to a variety of truck crops in the Gulf district 
of Mississippi and Louisiana. 

A large infestation of the gipsy moth has been located within 5 miles of the 
eastern border of the barrier zone in Connecticut. 

An insect new to this country has been found attacking wistaria at Greenwich, 
Ccxm. It is Lecanium excrescens Ferris. 



GENERAL FEELERS 

GRASSHOPPERS (Acrididae) 

North Eakota. J. A. Munro (February 17): The grasshopper situation remains 

unchanged. The heavy snowfall over the State has, I believe, rendered such 
protection that very few of the eggs will be injured by the cold. 

South Lakota. H. C. Severin (February 20): Eggs of grasshoppers passed the 

winter in excellent condition. Bee fly larvae and meloid larvae are fairly 
abundant, but not abundant enough to make any material difference so far as 
grasshopper prospects for next spring are concerned. If weather conditions 
are favorable to grasshoppers in the spring and unfavorable to plant growth, 
we expect a large amount of grasshopper damage in South Lakota during the year, 
However, I do not believe that the damage will be so severe as it was in 1931. 



-6~ 

Iowa. C. J. Drake (February 17): Grasshoppers are scarce. No serious outbreak 
is expected, although there will probably be a few small areas to treat. 

Missouri. L. Haseman (February 22):" With the favorable situation as regards 
grasshoppers last fall, coupled with wet, cold winter, hoppers are not 
threatening. 

Colorado. G. M. List (February 24): Moderately abundant in localities in eastern 
Colorado. 

New Hampshire. L. C. Glover (February 23): Mr. Conklin reported on January 30 
that active nymphs of Chortophaga sp. were observed on a lawn. 

Florida. J. R. Watson (February 20) : Schistocerca americana Prury is moderately 
abundant at Gainesville and Lake Alfred. 

tfHITS! GROTS l^ Phyllophaga spp.) 

Pennsylvania. H. E. Hodgkiss (February 28): White grubs have been found rather 
abundantly as pupae in the soil just above the plow- line. Farmers have re- 
ported that they are turning large numbers of them up, and that where this is 
done birds are very abundant following the -plow in the field. 

West Virginia. L. M. Peairs (February 17): White grubs are reported numerous 
in soil in various sections. 

Virginia. W. J. Schoene (February 18): Two complaints were received from Augusta 
County of severe injury to the sod by white grubs. 

Iowa. C. J. Drake (February 17): White grubs ere very abundant. Many serious 
reports of Brood A are expected. 

H. S. Jaques (February 21): An unusual abundance of white grubs has been 
observed and reported by some of our farmers in digging holes for fence posts. 

CEREAL AND FORAGE-CROP INSECTS 

- WHEAT 

HE S SIM FLY ( Pbytophaga destructor Say) 

Ohio. T. H. Parks (February 20): The only thing I have to report 'is the fact 
that the Hessian fly is very scarce in Ohio and that we have one of the 
lightest populations of this insect for many years. There is no indication 
that damage will occur anywhere in the State this summer. 

Iowa. C. J. Brake (February 17): The Hessian fly is moderately abundant. Monona 
County represents the most heavily infested part of the State. 

Missouri. L. Haseman (February 22): Most of the wheat area has many Hessian 
flies and winter has not been particularially hard on them. 



CHINCH BUG- ( Blissus leucopterus Say) 

Illinois. W. P. Flint (February 21) : The chinch "bug is present over all of 

.the State with the exception of the extreme northern and southern ends 

Recent counts show a very low winter mortality, "better than 90 per cent of 
the "bugs "being alive at this time. 

Iowa. C. J. Drake (February 17) ':'" The chinch bug is moderately abundant. It will 
probably do some damage-- spotted — in 10. to 16 counties, in small areas. >■ 
H. E. Jaques (February 2l): Chinch bugs are apparently showing up in con- 
siderable abundance. During a warm spell just preceding our last freeze they 
were craY/ling about in last summer's heavily infested area in the southern 
part of Henry County in large numbers. 

Missouri. L. Haseman (February 22): Two cold spells coming with sudden temperature 
drops and the more or less continuous wet weather are not favorable for the 
chinch bug. . »..,.,,.- ; - :--•'• ... 

Kansas. H. R. Bryson (February 23): More chinch bugs went into hibernation at 

Manhattan during the fall of 1932 than was the case the preceding year. Counts 
made to determine the number of bugs hibernating in the vicinity of Manhattan 
showed an average of 40 bugs to the bunch of native prairie grass, with a 
mortality of 5 per cent. The dryness of the winter in the State has been 
conducive thus far to the successful overwintering of the bugs. . ■.. . 



Oklahoma. C. F. Stiles (March 1,):; Chinch bugs were quite numerous in bunch grass 
.along the roadside in. Pawnee County before the last cold snap, but I have not 
had time to make a ..survey since that time. 



. WHEAT JOINT WORM ( Harmolita tri-.tici Fitch) 



Oregon. Monthly letter of the Bureau of Entomology, No. 224 (December 1932): 
T. R. Chamberlin, November, Forest Grove, Oreg. , made an examination cf the 
fall collection of wheat stubble from the sample farm in the Molalla district 
and found Harmolita tritici present in 28.2 per cent of the straws. The 
following parasites were also present; in the percentage indicated; Ditropinotus 
aureoviridis Cwf d. , 20.3 per cent; Eurytoma parva (Girault) Phillips, 48.2 per ce 
Eupelmus allynii (French) and Eupelminus saltator Lind. , 1.8 per cent; 
Calosota metallica Gah. , 0.5 per cent; undetermined parasites, 1 per cent; 
total parasitization, 71.8 per cent. -*-** examinations showed that ^8 other 
Eurytoma had been destroyed by secondaries as follows: Ditropinotus, 56; 
E. allynii and S. saltator , 15; Calosota, 4; undetermined parasites, 3. The 
original parasitization of Eurytoma in the cells as counted in the fall was 
thus 52.9 per cent. It was also found that 118 other Harmolita had been 
destroyed by Eurytoma larvae which had entered more than one cell. The number 
of Harmolita originally present was, therefore, greater by 118 than was 
indicated by the fall count and the total destruction of Harmolita by Eurytoma 
was 56.1 per cent and by all parasites was 73.1 per cent. *** Comparing the 
parasitization in the fall collection from the sample field in 1932 with that 
in the corresponding collection in 1931, the total destruction of Harmolita 
by E. parva has increased from 45.2 to 56.1 per cent. *** By the middle of the 
month most of the H. tritic i were still pupae, whereas in 1931 practically all 
had pupated by the first of the month." ■

LADYBSETLES (Coccinellidae) 

Oregon. B. C. Mote (February): B. G. Thompson reports on January 6 that he 

visited Peterson's Butte, near Corvallis, and found an unusually large cache 
of ladybird beetles. They appeared to be mostly Hippodamia convergens Guer. , 
and seemed to have survived the cold weather in December in fine shape. More 
than 300 specimens were examined and only one was found dead. 

Iowa. H. E. Jaques (February 21): Ceratomegilla fuscila b ris Muls. is appearing 
in student collections in numbers that would .indicate it to be quite abundant 
out of doors. 

A LEAFHOPPER ( Agallia sanguinolenta Prov.) 

New Hampshire. L. C. Glover (February 23): (Notes from Mr. Conklin, January 16): 
A very warm day. The leafhopper Agallia sanguinolenta was found beneath the 
remains of flower plants and appeared quite active when disturbed. 

ALFALFA - 



CLOVER LEAF WEEVIL ( Hyp era punctat a Fab.) 

California. A. E. Michelbacher (February 19): Throughout the winter a very few 
alfalfa weevil larvae have been collected from time to time at Pleasanton and 
Niles. However, the larvae of the clover leaf weevil were collected with 
considerable ease, and at the present time they are fairly numerous. 

GRASS 

RANGE CATERPILLAR '(H emileuca oliviae Ckll.) 

New Mexico. 0. L. Barnes, Monthly Letter of the Bureau of Entomology, No. 224 
(December 1932): Range conditions in northeastern New Mexico were poor over 



practically all- the area observed, due principally to lack of rainfall during 
the summer and early fall. *** The entire range caterpillar area visited had 
"been very closely grazed, grasses or other plants suitable for egg deposition 
were very scarce in many localities, and apparently the larvae of the range 
caterpillar had died in large numbers over a considerable portion of the area 
visited. *** Range caterpillar eg^s could be found after a brief search at 
almost any point in the caterpillar territory, but eggs in concentrated 
quantities suitable for mass .collecting were observed in only three general 
localities — near Greenville, in Union County; Mills, in Harding County; and 
Wagon Mound, in Mora County. Grama and other grasses were rather abundant and 
weather conditions had been more suitable in these areas. By far the best 
collecting area- of all was located about 4 miles south of Wagon Mound. It was 
estimated at the laboratory that approximately 8,000,000 range caterpillar eggs 
were collected this season (for breeding the 'parasite Anastatus semiflavidus 
Gahan) . 

SUGARCANE 

A WEEVIL ( Anacentrinus sub nu das Buchanan) 

Louisiana. W. E. Hinds (February 2l): The sugarcane root-stock weevils have been 
found abundantly in larval and pupal stages, especially in third-year stubble 
of POJ 213 cane at Baton Rouge. 

SUGARCANE BORER (Diatraea saccharalis Fab.) 

Louisiana. W. E. Hinds (February 21): The sugarcane borer larvae in hibernation 
had been reduced in numbers very greatly by rather unusually thorough burning 
off of the cane trash through the latter part of January and first week of 
February. The freeze in the second week of February increased the mortality 
decidedly among the larvae surviving at that time. Trichogramma minutum 
developing in Sitotroga eggs survived exposure to 17° F. and considerable 
numbers emerged thereafter. These specimens were laboratory material in two 
stages of development and were placed in the weather-apparatus shelter in the 
field before the temper: ture began to rise. The freeze delayed by about five 
days the emergence of wasps ready to emerge.

Virginia. W. J. Schoene (February 13): Eggs of apple aphids are difficult to 
find on fruit trees. 

West Virginia. L. M. Peairs (February 23): Fruit aphids are reported at Morgan- 
town — even distribution, moderately abundant. 

Illinois. W. P. Flint (February 21): There is a great variation in the number of

number of eggs in the central and southern pr.rt of the State. 

Iowa. C. J. Drake (February 17): Fruit aphids are moderately abundant. 

Missouri. L. Hasemo.n (Febriary 22): Aphid eggs are less abundant than usual but

Cornelia. There is a fair winter survival of hibernating larvae - no pupation 

. yet. 

Missouri. L. Haseman (-February 22): A heavy crop of the codling moth is hiber- 
nating. The recent blizzard resulted in a mortality of 20 per cent above

New York. S. f« Harman (Ma'rch l) : The San' Jose scale is moderately abundant in 
western New York. 

West Virginia. L. M. Peairs (February 23) : The San Jose scale is moderately 
abundant at Morgantown. ( 

Virginia. W. J. Schoene (February 18): We are searching for trees infested 

with the San Jose scale for testing out spray mixtures. Thus far we have not 
been able to locate any'. infest e.d trees in the State. The scale seems to have 
practically disappeared from unsprayed trees. . 

North Carolina. Z. P. Metcalf (February 21): The San Jose scale is moderately 
abundant. It is apparently not so abundant as it has been in former years. 

Georgia. 0. I. Snapp (February 20): On February 9 the minimum thermometer at 

Fort Talley recorded 11.9° F. above zero. According to our data on the effect 
of cold weather on. the San Jose scale, that temperature was sufficient to 
reduce materially the infestation on peach trees in this locality. Figures 
on the percentage of scale killed by the recent cold weather will be available 
early in March. 

C. H. Alden (February 22): The San Jose scale is moderately abundant at 
Cornelia. There has been intermittant breeding throughout the winter months. 
Crawling young were observed in January. 

Florida. J. R, Watson (February 20): The San Jose scale is moderately abundant 
in Gainesville. 

Illinois. W. P. Flint (February 21): Low temperatures have killed probably 90 
per cent of the peach buds and have .had some effect in reducing the numbers 
of the San Jose scale, although actual counts have not been possible in many 
localities. 

Wisconsin. E. L. Chambers (February 27): Since our last report was made on the 
San Jose scale, we are finding additional outbreaks in Jefferson, Waukesha, 
and Milwaukee Counties, indicating that this insect is spreading in Wisconsin 
aided by the hot, dry summer and the comparatively mild winter. 

Iowa. C. J. Drake (February 17): The San Jose scale is moderately abundant. It 
is spreading to the southeastern part of the State, and was found in Ees Moines 
and Ames last fall. 

Missouri. L. Haseman (February 22): Recent 'counts of the San Jose scale at 

Columbia .on Japanese quince ^show 86 per cent mortality of winter-stage nymphs. 

Alabama. J. M. Robinson (February 17): The San Jose scale is moderately abundant 
at Auburn. 

Mississippi. C. Lyle (February 21): A. perniciosus was found on Mahonia from

abundant in southwestern Idaho. Very little winter mortality. 

Utah. Or. F. Knowlton (February 20): Eggs, only, of the San Jose scale in 
northern Utah. 

California. E. 0. Essig (February 20) I The San Jose scale is moderately 
abundant in a few orchards. 

COMMON BED SPIDER (Tetranychus telarius L.) 

Pennsylvania. H. E. Hodgkiss (February 28): Red spider eg^s are not so abundant 
as last year and we do not look for serious infestations except in occasional 
• orchards.

PEAR PSYLLA (Psyllia pyricola Foerst.) 

New York. S. W, Herman (March l) : The pear psylla is moderately abundant in 
western New York. 

PEAR TKRIPS ( Taenio thrips inconsequens Uzel) 

California. F. H. V/ymore (February 21): Dr. S. F. Bailey reports that the pear 
thrips, or prune thrips ,was collected for the first time this spring on 
February 15 in the Healdsburg section, and on February 17 in the San Jose 
section. 

PLUM 



A THRIPS ( Leptothrips m ali Fitch) 

California. L. M. Smith (February 27): L. mali , a large, black, predacious 

thrips, was found in considerable numbers, apparently hibernating, under old 
shells of the brown apricot scale, Lecanium corni Bouche, on French" prune tree; 
at Linden, on February 22. The maximum occurrence' was eight thrips under a 
single scale. The present winter has been abnormally cold, but apparently has 
not reduced the survival of this beneficial thrips. 

PACIFIC RED SPIDER ( Tetranychus pacificus McG.) 

California. L. M. Smith (February 27): Considerable numbers of T. pacif icus were 
discovered hibernating under old shells of the brown apricot scale, L. corni , 
on French prune trees at Linden, on February 21. The maximum occurrence wa.s 
21 spiders under a single scale. 

RASPBERRY 

RED-NECKED CANE BORER ( Agrilus ruficollis Fab.) 

Wisconsin. E. L. Chambers (February 27): An item which may be of interest is 



the finding of the red-necked cane "borer showing up in our packing house in- 
spections of raspberry plants, inci da tin's that this insect was quite prevalent 
and that some of the fields which were certified as having only a trace earlier 
in the summer when they were inspected developed to have heavier infestations 
during the late fall,, and con'seauently a special notice was sent out to all 
the nurserymen calling their attention to the pest and reminding them that it 
would be necessary to sort these out carefully and carry on the control 
. measures recommended, 

A MARCH FLY ( Bibio albipennis Say) 

New York. C. E. Crosby. (November 12): This insect is abundant around raspberry 
plants. Many larvae were received. 

RASPBERRY ROOT BORER (Bembecia marginata Harr.)

January 9. 

CITRUS . 

CITRUS APHID ( Aphis spiraecola Patch) 

Florida. J. R. Watson (February 20): The citrus aphid is considerably in evidence 
on young trees, and indications are that if the weather remains comparatively 
cool with sufficient rain to stimulate growth, and in the absence of heavy, 
dashing rains, this infestation may be quite heavy by March. 

MEXICAN FRUIT FLY 'A nastrepha ludens Loew)' 

Mexico. News Letter, Bureau of Plant Quarantine, No. 25 (January l) : Three 
adult flies were taken Dec. 9 in the traps operated on the premises in 
Matamoro.s on which a number of flies were taken last month. No other flies 
were taken in the 2C 5' traps operated on the 1 74 other premises on which, traps 
were operated. The fruit arriving in Matamoros from the interior of Mexico 



-*14* 

has shown a very light degree of infestation during the past two months. It 
will he recalled that no infested fruit was recovered in Octoher, that being 
the first month to elapse with no infested imported fruit "being recovered 
since a full-time inspector was assigned to Matamoros in 1929. Only four 
imported oranges were found' infested during" November. Sight larvae were 
■ taken from these oranges, which originated in Montemorelos, in the State of 
Nueva Leon. Whether the absence of infested fruit in Matamoros is the result 
of climatic conditions at the points of origin, control measures carried out 
by the growers, or closer culling at the time of shipment, is not known. The 
four infested oranges were contained in, shipments of four cars of bulk oranges 
from Montemorelos. (No. 26 February l): Four carloads of oranges, in bulk, 
were received in Matamoros during January from Montemorelos. Some 6, COO of 
these fruits which had spoiled were taken Up from the various stands throiighou 
the city. Examination showed 22 of them to be infested with larvae of the 
fruit fly. Sixty-seven larvae were recovered. Oranges were retailing during 
the month at 1 cent (Mexican) each, or about one-third of a cent American 
money. As a result of the low prices, oranges were scattered all over the 
city with a corresponding danger of ' the establishment of a local " infestation. 
The second application of nicotine-molasses bait spray to the trees of 
Matamoros was completed on the 24th. While no A. ludens have been taken in 
the traps in Matamoros since the first application of the bait was completed, 
10 A. pallens were taken during December,. 

RED SCALE ( Chrysomphalus aurantii Mask. ) 

California. H. J. 'Ryan (February 23): The red scale shows a winter mortality 
of about 50 per cent. This is a more normal condition than was re- 
ported a year ago, when the mortality was unusually high. 

FLORIDA RED SCALE ( Chrysomphalus aonidum L.) 

Florida. J. R. Watson (February 20):. The Florida red scale is moderately abundan'

CITRUS BLACKFLY ( Aleurocanthus woglumi Ashby) 

Canal Zone. James Zetek, Monthly Letter of Bur. of Ent-i, U.S.D.A,, No. 224 

(December): Adults of Sretmocerus serius Silv. were liberated September last 
year at Fort Amador, at a place near Juan Diaz, and at a place called La 
Sabanilla, near Juan Diaz. *** At Fort Amador the' limes are fairly clean of 
woglumi . The some was true at Ucros plc-ce, beyond Juan Diaz, At La Sabanilla 
where the citrus trees were in an abandoned state and heavily infested,, I was 
almost unable .to get any woglumi , and such leaves as I did get had the exit 
holes of the parasite. Live parasites were seen at all three places. 

CITRUS WHITEFLY ( Dialeurodes citri Riley & How.) 

Florida. J. R. Watson (February 20): The citrus whitefly is moderately abundant 
at Gainesville and Lake Alfred. It is not parasitized by entomogenous fungi 
as it was last year at this time, although fungi are in evidence. 

Mississippi. C. Lyle (February 21): A rather heavy infestation of D. citri on 
cape jasmine was reported from McComb on December 2, 1932, and on Camellia 
from Bay St. Louis on January 2, 1933..

California. H. J. Ryah (February .23) : Citrophilus mealybug control by the 
■ Australian parasites, Coccophagus gurneyi Comp . and Tetracnemus pretiosus 
Timb. has continued to be particularly effective. This mealybug is no longer 
considered, a peat of major importance. 

CI THUS RUST MITE ( Phyllocoptes oleivorus Ashm.) 

Florida. J. R. Watson (February 20): The citrus rust mite is moderately abundant 
at Lake Alfred,, rather more so than usual for this time of year. 

CITRUS RED SPIDER ( Paratetranychus citri McGregor) 

California.. H. J. Ryan (February 23): The red spider, P, citri , was exceptionally 
severe in 1932 and is carrying over in sufficient 'numbers to warrant the pre- 
diction that infestation will again be heavy in 1933. 

FIG 

RAISIN MOTH ( Ephestia figuliiella Greg.) 

California. Monthly Letter of Bureau of Entomology, U.S.D.A., No. 224 (December): 
The work of Dwight F. Barnes in fig orchards and drying yards near Fresno durin, 
the past season has just been summarized by Perez Simmons, who estimates that 
during the past season fig growers lost about $216,000 in actual cash, mostly 
as a result of deductions because of infestations by the raisin moth. It is 
believed that a large part of this loss can be prevented by the use of shade 
cloths in drying yards. 

DATE 



PARLATORIA DATE SCALE ( Parlatoria blanchardi Targ.) 

California. News Letter', Bureau of Plant Quarantine, No. 26, (February l): No 
infestations were found outside the areas already known to be infested. In 
the lute -growing areas 301,072 palm inspections were mr.de, and in outside areas, 
11,610. Four infested date palms were found. One of the 4 palms was found in 
Arizona, near Phoenix. It had been found infested previously and treated but 
obviously some live scale- remained. The palm was dug out and destroyed. The 
remaining 3 were found in the Imperial Valley in California. One of the 3 
showed live scale and was -defoliated and sprayed. Only single dead scales were 
found on the others and they were not treated. No scale was found during the 
• year in the Coachella Valley, the principal date-growing area. In the Imperial 
Valley in California an inspection was made of ornamental palms other than date, 
and 33 Canary Island and 4 fan palms were found infested. These were defoliate 
and sprayed. Four of the Canary Island palms showed a recurrence due to the 
fact that scale had penetrated and settled on unexpanded leaves in the bud when 
they were protected from the spray. These palms were cut back again and 
sprayed.

VEGETABLE WEEVIL ( Listroderes obl.iquus Gyll.) 



Mississippi. C. 'Lyle (February. 21): Beginning on -November 19, 1932, when we 
received the first specimens of the vegetable weevil since early summer, 
this insect has 'attracted more attention in Mississippi -during .the fall 
'■■■ and winter -months-, than any'' other -...species.--. Serious damage to turnips and 
mustard has 1>een reported from many localities in the southern three- 
fourths of the State throughout -the winter, while cabbage, spinach, car- 
rots, and other vegetables have been severely damaged at various places 
in southern Mississippi- during the past few weeks. On February 1 a num- 
ber of adult specimens of D. duodecimounctata were collected from a gar- 
den in Laurel, Jones County.'- 'Some larvae of the vegetable weevil -were 
sent at ■ the same time. The correspondent indicated that severe injury 
had been caused to cabbage, turnip greens, beets, and spinach, most of 
which had undoubtedly been.. -caused by the weevil, but possibly some by 
the cucumber beetles. 

Louisiana. W. E. Hinds (February 21): The vegetable weevil is now distrib- 
uted throughout Louisiana and had appeared in destructive numbers on a 
variety of crops before the occurrence of the freeze.

each year." 

CABBAGE 

CABBAGE WORMS 

Florida. J. R. Watson (February 20): Cabbage worms, which were so injurious 
last year, have been conspicuous by their absence this winter.

been stean-sterilized. Probably introduced in manure. 

STRAWBERRY 

STRAWBERRY PAM2RA ( Orthaea vincta Say) 

Florida. J. E. Watson (February 20): The strawberry pamera, which was so de- 
structive last winter, has been giving trouble only in the southern part 
of the State around Plant City, but they're not nearly so bad as last 
year. On the other hand, we have not had the foggy mornings that we had 
last winter, with the result that the entomogenous fungi have not been 
nearly so much in evidence. In other words, they have been abotit as 
dormant as usual in the winter time. 

STRAWBERRY ROOT WEEVIL ( Brachyrhinus ovatus L.) 

New York. S. 77. Harman (March l): The strawberry root weevil is moderately 
abundant in western New York. 

BEST LEAFHOOPER (Eutettix tenellus Bale. ) 

Idaho. R. W. Haegele (February 20): Weather conditions in southwestern Idaho 
in December probably increased greatly the winter mortality of the beet 
leafhopper. With the ground practically bare of snow cover and tempera- 
tures ranging from— 10° F. to — 15° F. , overwintering conditions were ex- 
tremely unfavorable. Absence of snow with lower temperatures in southern 
Idaho during December made overwintering conditions unfavorable there 
also. During February, 1933, temperatures dropped to- -15° to - 25° F. with 
a 6 to 8 inch covering of snow on the ground. Definite information re- 
garding winter mortality will be available in March from Dr. P. N. Annand 
of the Bureau.

FOREST AND SHADS-- TREE INSECTS 

BRO TOT- TAIL MOTH ( Nygmia uhaeorrhoea Don. ) 

New England. Monthly News Letter, Bureau, of Plant Quarantine, No. 26 (February 
1): The following information has been prepared from a survey of the 
"brown-tail moth records at the Greenfield office. In general, the "brown- 
tail moth infestation in New England during 1932 was somewhat lighter 
than during the previous year. This is "based on field observations made 
during the summer months and on the number of hibernating webs cut from 
the trees during the winter. A summation of the records at the office 
shows that from 1932 to and including the spring of 1332 there were over 
10,000,000 webs cut from trees in Massachusetts, New Hampshire, and Maine. 
Records are available for towns in Massachusetts . from 1922, but in New 
Hampshire they begin with 1930, and for Maine with 1931. In 1930, a total 
of 1,133,379 webs were cut, 689,684 of which were in Massachusetts, and 
493,695 in New Hampshire. In 1931, a total of 1,656,045 webs were cut as 
follows: Massachusetts, 661,613; New Hampshire, 652,768; and Maine, 
341,664. In 1932 the total number of webs cut was 896,469 as follows: 
Massachusetts, 314,919; New Hampshire, 513,760; and Maine, 67,790. There W3re^ 
, of course, other webs cut by individuals, of which we have no record. In 
Massachusetts the webs are cut annually by the local moth superintendents, 
and this is generally done quite thoroughly. In New Hampshire and Maine 
the work is done by the State organizations and by towns in a. few cases 
when advised to do so by the State officials. Daring 1932 the infestation 
was scattering and light in the eastern half of Massachusetts except for 
heavy infesta.tion in southeast em and northeastern parts of the State. 
In New Hampshire, the southeastern section, along the New Hampshire and 
Maine State lines, the Atlantic Ocean, and west to and including the Merri- 
mac Valley as far north as Lake Winnif^csaukee, was ra,ther heavily infested, 
and light infestations were found as far north as Bartlett, Conway, and 
Albany. The infestation in Maine was general and heavy in spots through- 
out the southwestern section including the area from Lewiston and Auburn 
directly south to the Atlantic Ocean and westerly from Lev.iston and Auburn 
through Poland, Casco, and Sebago to the New Hampshire State line. In- 
festation was observed as far easterly as Castine on the Penobscot River, 
where 7,000 webs were cat. 

New Hampshire. L. C. Glover (February 23): Notes from Mr. Conlclin - Two local 
outbreaks of brown-tail moths have been reported by Mr. Osgood. One is in 
Laconia and the other in Alton, from Alton to Alton Bay. 

GYPSY MOTH ( Porthctria di suar L. ) 

Maine. News Letter, Bureau of Plant quarantine, No. 26 (February l): Two 

gipsy moth egg clusters \~ere found on spruce wreath material at Woburn, 
Mass. The spruce branches originated in southern Maine and were inspected 
at \7oburn prior to being ma.de up into finished wreaths that were to be 
shipped to New York City. This is the first record for several years of 
egg clusters 'being found on materials which were to be used in the rnanu- 

* facture of wreaths. 



-21- 

Now Hampshire. News Letter, Bureau of Plant Quarantine, No. 25 (January l): 
Mr. McNerney reports the finding of a gipsy moth egg mass on a crate of 
rough slabs containing laurel wreaths. Five such crates were moving to 
Boston from a point in the infested area in New Hampshire. 

Connecticut. News Letter, Bureau of Plant Quarantine (February 1): A report 
has been received from the State of Connecticut indicating that the State 
force have discovered a large gipsy moth infestation in woodland in the 
town of Wolcott. They have already treated over 4,500 egg clusters in an 
area of about a square mile and a large amount of additional work will 
have to be done before work is completed there. The presence of so large 
an infestation within 5 miles of the eastern border of the barrier zone 
might prove to be serious had it not been discovered, for there would be 
considerable danger of the small gipsy moth caterpillars drifting into 
the barrier zone during the spring if the wind were blowing in a westerly 
direction. As no Federal funds are available for work east of the bar- 
rier zone and as there are not sufficient State or town funds appropri- 
ated to do a great deal of woodland scouting, there is no means of know- 
ing whether or not similar infestations exist in other localities near 
the eastern border of the barrier zone.

Kansas. H. 3. Hungerford (February 20): The fall canker worms are abundant at 
Lawrence. They were emerging in December. 

K. R. Bryson (February 23): Emergence of the fall canker worms began 
about the first of January and continued throughout the month. The peak 
of the emergence of this brood occurred January 31. The spring brood 
began to emerge the last week in January, but, to date, has not reached 
the height of its emergence. 

RESPLENDENT SHIELD BEARER ( Coptodisca splendoriferella Clem.)

frame house 44 years old located in Little Falls. About 10 years ago we 
noticed that every morning in the garret there were numerous bugs lying 
about on the floor. They were swept up every day but the quantity was 
not enough to be especially noticeable. Last fall a new tenant complained 
of the quantity ofthis same kind of bug that seemed to appear during the 
night and lay scattered all over the house in the morning. From conversa- 
tions with the tenants they explained that you could sweep under any of 
the baseboards, where there were spaces between the baseboard and the 
floor, and find some of these bugs. (Det. E. A. Back.)

'THE MORE TffOHTANT RECORDS FOR ?-tARCH, 1933" 

The army cutworm is causing damage to wheat and oats in central and 'south- 
ern Kansas, and the entire northwestern part of Oklahoma. 

A hefevy infestation of Hessian fly flaxseeds; extends across central Missou- 
ri. Infestation is also' rather heavy in south-central Nebraska. Wheat sown af- 
ter the fly-free date in the East.. Central States appears to. "be in good condition. 
That sown prior to this date in. western Illinois is carrying a 36 oer cent in- 
festation. . 

Survival of the sugarcane borer, is unusually light in Louisiana owing ap- 
parently to severe cold in early February. 

In the northern part of the East Central States codling moth mortality ran 
as high as 50 per cent. This is r>robably s associated with temperatures ranging 
below 25° below zero during the winter. 

The first adult of the oriental fruit moth emerged in southern Georgia 
March 12 and in South Caroline, March 24. No emergence has been reported from 
the States farther north'. 

The plum curculio started leaving hibernation in numbers during the last 
week in March in Georgia. This is about the normal time for emergence. 

Considerable damage' has been done to orange %r the green citrus aphid 
throughout a large part of the peninsula of Florida. The damage, however, is 
not so severe as in previous outbreaks. 

Buffalo gnats are again appearing, in the. Mississippi Delta. and a fev deaths 
of livestock have been reported.

have not been determined at the present writing* Injury began very early in 
the southern part of the State. The worms become active at Kingman when the 
temperature began to rise about two days following a drop to 14 degrees below

in severity; and Reno, Russell, and Saline Counties, where injur;/ has been 
least severe. -Two "reports from Salina and Mont Hope stated that the worms 
were injuring alfalfa. -They are- rather' plentiful at- Manhattan, but thus far 
no injury has been reported. 

Oklahoma. C. F. Stiles (March 22): Cutworms are very abundant in wheat and 

alfalfa fields in 'western Oklahoma. The western army cutworm (C. auxiliaris ) 
at this time is present in large numbers in Noble, Garfield, Blaine, and 
Major Counties and. from meager reports I understand that the entire north- 
western part of the State is infested. Some wheat fields hove been severely 
damaged and alfalfa is showing effects of injury. Owing to the wide dis- 
tribution of these pests over the fields, farmers do not think it' is practical 
to poison at this time„ If weather conditions are favorable for their devel- 
opment, we may expect serious damage to some wheat fields. 

Louisiana. W. E. Hinds (March 28): Cutworms are moderately abundant in gardens 
and on young corn at Baton Rouge. 

Utah. G. F. Knowlton (March 21): Cutworms are modertely abundant in some 
pastures in Tooele County.

Clemson College March 18. 



WHITE GRUBS ( Phyllophaga spp . ) 

West Virginia, L. M. Peairs (March 23): White grubs are moderately abundant' at 
Morgantown. They are beginning to show in early plowing. 

Indiana. J. J. Davis (March 27): Anticipate white grub trouble in 1933. 









Illinois. W. P. Flint (March 22): From present information on white grub damage 
and a partial survey made in the fall of 1952, nearly one-fourth of the fields 
in northern Illinois show a population sufficient to cause damage to corn 
during the summer of 1933. These grubs are a mixture of both Brood A and 
Brood B, Brood A being by far' the more abundant, although serious damage from 
Brood B may also occur during the early part of the season. Population counts 
in this section of the State show that most timothy and blue -grans fields 
carry from 10 to 35 grubs per square- yard-. ■ 

J. H. Bigger (March 24): White grubs are very abundant -about the same as in 
1930 in western Illinois, - . . 

Iowa. C. J. Drake (March 21): -White grubs, Brood A, are very abundant. 

Wisconsin. C. L. Fluke (March 24): The white grubs should be unusually destructive 
this season, at the second year of the cycle, Brood "A", is due in Wisconsin. 






-31- 

Missouri. L. Haseman (March 22): Two species of June beetles were abundant in 
the surface 6 inches of soil at Columbia, March 15 to 18.

middle of March, Phyllophaga congrua/ adults were flying in quite large numbers. 

WI REWORKS (Elateridae) 

Kentucky. W. A. Price (March 24): A corn wireworm ( Melanotus sp.) was found doing 
serious damage to lettuce at St. Matthews on March 10. 

Alabama. K. L. Cockerham (March 14) : Larvae of Eet erode res laurentii Guer. were 
found very plentiful in experimental plats of corn which had been planted on 
March 1 at Foley. The corn was sprouting and some of it was just coming 
through the ground. The average for the l/4-acre plrt was nearly 1 larva 
per linear foot. Examination of the sprouting grain showed that no damage had 
been committed. It seemed that the larvae were just locating the grain and 
collecting near it. Feeding will no doubt begin in the very near future. The 
warming of the soil will no doubt see great activity and feeding of the larvae. 
Ra.ndom examinations of the Irish potato plats showed that there was apparently 
no damage by this insect to the potato seed pieces. Larvae were comparatively 
scarce in the rows. The plats examined were planted on Feb. 15 and 22. 

Missouri. L. Haseman (March 22): Recent observations indicate a scarcety of wire- 
worms in central Missouri. 

Oklahoma. C. F. Stiles (March 22): Wireworms are doing considerable damage to 
early gardens in Bryan County. They are moderately abundant in gardens in 
south-central Okl aho ma . 

California. A. E. Michelbacher (March 19): Wireworms ( Anchastus cinereipennis 
Esch. ) are scarce at Rio Vista. • 

A MOLE CRICKET ( Scapteriscus acletus R. 4S.) 

Mississippi. C. Lyle (March 23): On Feb. 21 a correspondent at Biloxi, Harrison 
County, sent us specimens and wrote as follows: "About two or three days 
after I plant seed these crickets, or "puppies", run through them and cut 
them out . " 



CEREAL AND FOR ACE-CROP I 

WHEAT 

HESSIAN FLY (Phyjtpphaga destructor Say) 

Ohio. T. H. Parks (March 24): The Hessian fly is scarce. 

Illinois. J. H. Rigger (March 24): Ninety per cent of the wheat was seeded 

after the safe-sowing date in western Illinois last fall. Luring the winter 

it has been found to contain 3.2 per cent infestation. The other 10 per cent 
is found to have 36 per cent infestation. 



-32- 

Nebraska. M. H. Swenk (March 1 to 25) : . The infestation "by the Hessian fly in 
south-central Nebraska shows considerable strength at this time. The old 
volunteer wheat is especially heavily infested in some localities. In northern 
Webster County the surviving main crop of wheat shows an infestation of about 
2 puparia per plant. 

Iowa. C. J. Drake (March 21): The Hessian fly is moderately abundant in Monona 
Countv but much lighter elsewhere. 

Missouri. L. Kaseman (March 22): The situation is rather alarming across central 
Missouri and in southeastern Missouri. The heavy crop of "flaxseeds" seem to 
be passing the winter in good condition..

Ohio, T. H. Parks (March 24) : The chinch bug is moderately abundant and threatens 
damage in some localities. 

Iowa. C. J. Drake (March 21): Chinch bugs are moderately abundant. In 15 or 16 
counties the infestation is spotted. 

H. E. Jaques (March 23): There is an abundance of chinch bugs on warm days in 
southeastern Iowa, and in limited areas in southwestern Iowa. 

Missouri. L. Haseman (March 22): Recent counts in some clump grasses indicate 

that approximately 40 per cent of the adults are dead. However, large numbers 
are surviving the winter. 

AN ASCTIID MOTH ( Apantesis phalerata Harr.) 

Nebraska. . M. H. Swenk ^March 1 to 25): During the second week in March cater- 
pillars of A. phalerata. occurred in great abundance in Scotts Bluff County, 
and were reported as destroying the wheat in some fields in that locality. 

ALFALFA 

ALFALFA WEEVIL (Kyp_era postica Gyll.) 

California. A. E. Michelbacher (March 19): Starting about Feb. 22, larvae 
could be collected with considerable ease at Pleasanton and Mies. Since 
that time they have become more abundant . In one of the more heavily infestei 
fields at Pleasanton 22V larvae were collected per 100 sweeps on March 17 
whereas in a heavily infested field' at Mies 398 larvae were collected with 
a like number of sweeps on March 13. In the area around Tracy the weevil has 
made its appearance for the first time this season. At Tracy proper the first 
larvae were collected on March 17. Here in a field under observation 5 larvae 
to 100 sweeps were collected. At Vemalis, which is 12 miles from Tracy, the 
first larvae and adults were collected on March 9. At that time 12 were 
taken to 100 sweeps, while on March 17 the average per 100 sweeps was 40. In 
all there are eight fields in which we are making population studies, and in 
every one the population is rising from week to week. The alfalfa at the 
present time is from a fourth to probably a little more than three-eighths 
grown.

OOWPEA APHID ( Aphis medicaginis Koch) 



California. A. E. Michelbacher (March 19): In the alfalfa fields at Vernalis 

aphids were collected in large numbers on the 17th of March. On the same date 
they were collected in rather large numbers at Tracy. 

SUGARCANE 

A WEEVIL ( Anacentrinus subnudos Buchanan) 

Louisiana. ¥. E. Hinds (March 28): The sugarcane rootstock weevil occurs 

abundantly and in all stages (except eges not found) in third .year stubble of 
P.O.J. 213 which was he ing destroyed at the middle of March. Among root stocks, 
71.2 per cent were infested. Among the eyes 31.5 per cent had been destroyed. 
Among the weevil stages found the natural mortality was 29.5 per cent. 

SUGARCANE BEETLE ( Euetheola rugiceps Lee.) 

Louisiana. V J. E. Hinds (March 29): Sugarcane "beetle adults in hibernation are 
much more scarce than one year ago. Much less evidence of beetles feeding in 
August and early September planted cane was seen last fall, We anticipate but 
slight general damage this spring. 

A SCARAB ID ( Dyscinetus trachypygus Burn.) 

Louisiana. W. E. Hinds (March 28): During a period of warm nights at about the 
middle of March, some specimens of Dyscinetus trachypygus were flying in 
quite large numbers. 

SUGARCANE BORER ( Diatraea saccharaiis Fab.) 

Louisiana. W. E. Hinds (March 28): Sugarcane borer survival of hibernation is 
unusually light, due apparently to severe cold of early February followed by 
souring of cane and rapid decompostion of thicker parts of trash. Destruction 
6f tops by burning during January was unusually thorough also. Some complaint 
of deadhearts in young sprouts from planted cane due to borer larvae in the 
seed cane. First adult moth emerged from pupae taken from old corn stalks late 
$A -"February. . "..-..'. 

FRUIT INSECTS

Connecticut. 17. E. Britton (March 24): Fruit aphid eggs are scarce. 

Delaware. L. A. Stearns (March 25): Fruit aphid eggs are apparently somewhat 
less abundant than usual. 



-34- 

West Virginia; L. M. Peairs (March 23): Fruit aphid eggs are moderately abundant 
at Morgantown. Three species are present in undetermined proportions. 

Georgia. C. H. Alden (March 13): The green apple aphid is still in the err stage 
at Cornelia. 

Wisconsin. C. L. Fluke (March 24): Plant lice, especially those on fruit trees, 
do not appear to be so numerous this year as they were last- spring, since the 
eg~s are not anywhere near so numerous. 

Alabama. J. M. Robinson (March 21): The woolly apple aphid ( Brio soma lanigergm 
Hausm.) is moderately abundant on apple at Pisgah. 

Oregon. D. C. Mote (March 22): Fruit aphids on prunes in Albany were noticed

Delaware. L. A. Stearns (March 25): The San Jose scale is rather more abundant 
than usual, especially in un sprayed orchards. 

Virginia. W. J. Schoene (March 28): Frequent scouting in several localities in 
the State indicate a scarcity of the San Jose scale. It appears that the 
scale is being held in check "cy some parasite, as the infestation is declin- 
ing rapidly on unsprayed trees. It is only now and then that we have been 
able to locate a severe infestation, and then on young plants. 

West Virginia. L. M. peairs (March 23): The San Jose scale is moderately abundant 
on several isolated trees at Morgantown. 

Georgia. 0. I. Snapp (March 17): The average percentage of scale alive on 
February 4 was 92 - 1.34 and the average percentage alive on March 17 was 
75.2 i 0.9. This reduction of 22.3 per cent is attributed to the cold weather 
in February, when the minimum temperature was 11.9 degrees F. above zero. 

Indiana. J. J. Davis (March 27): The San Jose scale is moderately abundant. 

Iowa. H. E. Jaques (March 23): The San Jose scale is moderately abundant in Lyon,

Indiana. J. J. Davis (March 27): The oyster-shell scale is moderately abundant. 



- 35 - 

Wisconsin. C. L- Fluke (March 24): The oyster-shell scale is more abundant than 

usual and nearly every new scale has eggs under it, although by examination 

about half of them are dead. I ha,ve not examined very many scales, but those 
seen show the above condition.

Cornelia. 

Indiana. J. J. Davie (March 27): The codling moth is moderately abundant. 

Illinois. W. P. Flint (March 22): A recent examination of hibernating larvae 

showed a winter mortality of approximately 50 ner cent. In northern Illinois 
the mortality is probably higher, as temperatures of 25° below zero were 
experienced in that part of the State. 

Michigan. P. Hut son (March 22): The codling moth us overwintering in usual numbers 

Iowa. H. E. Jaques (March 23): The codling moth is moderately abundant in Clayton 
and Bremer Counties." 

Missouri. L. Haseman (March 22): The subzero weather early in February killed 

about a fourth of the exposed larvae at Columbia, and similar reports come from 
other parts of the State.

very abundant and have just resumed activity for the year. 



-36? 

LESSER PEACH BORER ( Aegeria pictipcs &. & R. ) 

Georgia. 0. I. Snapp (March 17): J. R. Thomson observed a female-tyvipo-siting on 

a peach tree today at Fort Valley. This is an unusually early record for that ^ 
insect to be on the wing. Most of the spring-brood moths emerge in April in this 
latitude. 

Alabama. J. M. Robinson (March 21): The lesser peach borer is moderately abundant 
on peach trees at Troy. 

ORIENTAL FRUIT MOTH ( Orapholitha molesta Busck)

Delaware. L. A. Stearns (March 25): No emergence' of the plum curculio as yet. 

South Carolina. F. Sherman (March 25): The first adult was jarred from plum 
at Clemson College, March 23. 

Georgia. 0. I. Snapp (March 1.7): A grower reports the first adult from hibernation 
at Fort Valley today. We have failed to capture any by jarring. A lighter 
than average infestation is anticipated on -account of the very light peach crop 
last year and the cold weather in February. - (March 23): Adults are now leaving 
hibernation in numbers. This is about the normal time for them to leave' 
hibernation, and consequently a second brood can be' expected this year unless 
abnormal conditions occur during the pupation season. Hiley peaches are in 
full bloom and Elbertas will be in full bloom within another week. Therefore, 
the curculio has appeared in peach orchards this year well in advance of the 
time for the petal-fall application of spray. 

W. H. Clarke (March 15): First adults were caught on jarring frames at 
Thomas ton on March 15.

PECAN CASE BEARER ( Mineola juglandis LeB . ) 

Georgia. E. G. Moznette (March 2l): The immature larvae of the pecan leaf ease- 
Dearer are commencing to emerge from their hibernating quarters and feeding 
on the "buds of the pecan in the vicinity of Albany. The emergence usually 
coincides with the swelling and opening of the buds in the spring. The 
activity of the buds at this time indicates that growth development is about 
ten days earlier than in 1932. 

PECAN COSSIB ( Cossula magnifica Stkr.) 

North Carolina. R. W, Leiby (March 27): The pecan co'ssid seems to be more 

numerous than usual. Larvae causing the damage are nearly full grown. The

-38- 

J. R. Watson (.March 27): The citrus aphid is seen everywhere in the 
peninsula part of the State. The damage to oranges has been considerable, 
but not nearly so great as during some other years. It. seems likely that there 
will be considerable damage- to tangerines. The Chinese ladybeetle, Leis , 
imported in 1924-25, is present in large numbers in an area over a radius of 
5 miles in Orange County. This ladybeetle, during the summer time when aphids 
are scarce, has been seen feeding on the extra-floral nectaries of Crotalaria 
striata , as well as on gum from injured citrus trees.

of the red Aschersonia (red whitefly fungus), an important entomogenous fungus 
that destroys whiteflies in Florida, has been reported from the Fort Pierce 
area on the Florida east coast by a correspondent.

Albany. The plants infested included Pittosporum, Nandina, Spiraea, rose, 
Euonymus, Buxus, Satsuma orange, grapefruit, Citrus trifoliata , and pecan. 
The office of State Entomologist, through its field Station located at Albany, 
has furnished colonies of Vedalia beetles ( Rodolia cardinal is Muls.) in 
controlling the scale.

VEGETABLE WEEVIL ( Listroderes obliquus Gyll.)* 

Mississippi. C. Lyle (March 23): . Complaints of injury to turnips were received 
during the past month from Neshoba, Stone, Leake, Attala, Holmes, Lauderdale, 
and Smith Counties. The most serious complaint, however, came from Hatties- 
burg in Forrest County from a correspondent who wrote as follows: "These in- 
sects have consumed several rows of carrots and are found eating into the root 
of this vegetable; they have also destroyed my parsley, mustard, and other

SUMMARY OF INSECT CONDITIONS IN BRAZIL FOR 1932 
Edson J. Hambleton 
Escola Superior de Agricultura e Veterinaria, Vicosa, Minas Gera.es 
(Unless otherwise indicated, notes refer to Minas Geraes) 



SUGARCANE 

A sugarcane froghopper, Tomaspis iiturata Lep. et Serv., without doubt 
was responsible for heavier losses in the Bonte Nova and Rio Branco zones 
this year. From February to May the damage was more noticeable when the fo- 
liage turned yellow and poor growth resulted-. Growers are inclined to be- 
lieve that the better mosaic-resistant varieties are more seriously attacked. 
Five species of other grasses growing in and near cane fields have been 
found to harbor and serve as successful food plants. In the State of Rio 
de Janeiro this insect also caused serious losses in the cane fields. (C. 
Moreira. ) 

Another sugarcane froghopper, T. indentata Walk., is evidently causing 
more injury than has been accredited to it heretofore. This species is wide- 
ly distributed in this section of the State. It confines its feeding to the 
foliage while T. Iiturata feeds on the roots, near -the surface of the soil. 

The sugarcane aphid, Aphis sacchari Zehnt., was observed this year for 
the first time in Ponte Nova, Rio Branco, and Vicosa. The infestation was 
quite generally distributed in Rio Branco, where considerable losses resulted. 

Pseudococcus srp. were more commonly encountered this season than hereto- 
fore in Vicosa sugarcane. 

Several specimens of Mahanarva indicata Walk, were intercepted at the 
College this year in a small shipment of seed cane from Campos, State of Bio 
de Janeiro. This froghopper has not yet been observed, in Vicosa. 

The sugarcane borer, Diatraea saccharalis Fab., was common through most of 
the growing season but did not cause serious losses. In fact several growers 
reported it as being less abundant in several varieties this year. Baring 
April three egg masses of Diatraea were found parasitized by Tricho gramma sp. 

The West Indian cane weevil, Metamasius hemipterus L. , caused complete 
loss in several hectares of newly planted cane in Rio Branco during February. 
In Vicosa this species has been observed only in banana. This insect caused 
considerable loss in a small banana .planting at the College during July. 

Two species of Thysanoptera, yet unidentified, were encountered in abun- 
dance in young cane at the College from March to May. 

A sugarcane stalk mite, probably belonging to the genus Tarsonemus, has 
been found to be quite common in the variety F. 0. J. 2714. It causes small 
blisters on the stalks while these are still covered by the leaf sheaths. 



-60- ' 

Practically 100 per cent infestation occurred in the College plots this nast 
year. Growers have been considerably alarmed over the appearance of this mite 
but are now beginning to believe that it is of little importance. 

A mite that has attracted more attention is one of the leaf mites, Tetrany- 
chus sp., observed for the first time in the following varieties: P.O.J. 2725,273 
and 2878. One field of 2725 was found with about one-half of the cane leaves 
moderately to heavily infested during February. 

COFFEE 

The coffee "broca," Stephanoderes hampei Ferr. , was observed for the first ] 
time in the State of Hinas G-eraes on February 8, 1932. Undoubtedly the insect 
has become slowly established in most of the counties bordering the State of 
Sao Paulo during the past few years. However, not until the above date had 
'there been any suspicion that the insect was present; it had disseminated over 
quite a large area. A survey was initiated in southern Minas G-eraes during 
April and up to the present writing (January 31, 1933) 33 counties have been 
found to be infested through the more important coffee zones of the State. In- 
jury to the. 1933 crop will undoubtedly be quite marked in the more heavily in- 
fested groves where means of control have not yet been undertaken. 

The green scale, Coccu s viridis Green, has received more attention by 
coffee growers this season. Many younger plantations were heavily infested 
toward the end of the year'. The coccinelid Azya luteipes Muls. and the fungus 
Acrostala albus Pr. proved of great benefit in holding the scale in check dur- 
ing the wet season. 

COTTON 

The pink boll worm, Pectinophora. gossyoiella Saund. , continues to be the 
most important cotton pest in this part of Minas. In spite of the fact that 
all possible meatis of reducing the infestation from one year to the next are 
thoroughly practiced, severe losses occur annually in Vicosa. Counts made in 
July on the College grounds showed 60 to 80 per cent infestation of bolls. 
According to C. Moreira, this insect is common in the principal cotton-grovdng 
regions of Brazil but is not responsible for serious losses. 

The cotton leaf worm, Alabama argil lacea Hbn. , appeared during January 
1932 in very small numbers. During the previous year parasites of the genera 
Spilocbx'lcis and Microgaster (det. C.F.17. Muesebeck) reduced the infestation to 
a minimum. For this reason we are of the opinion that very few adults escaped 
to infest the plantings of 1932. The cotton worm may be found widely distribute! 
throughout Brazil. 

The cotton aphid, Aphis gossypii Glov., was present from March to harvest 
time but never increased to such an extent as to warrant control measures. 
The coccinellid Neda sanguinea L. was present in large numbers feeding on the 
aphids. 

Dysdercus fernaldi Ballou and Euryophthalmus humilis Prury were both very 
common again this season in the cotton plots at the College. These "percevejos 1 * 
undoubtedly are important agents in the transmission of anthracnose and other 
cotton diseases. Practically 100 per cent of the bolls were fed upon by these 
insects. 



-61- 



The cotton "gorgulho," Gasterocorcod.es gossypii Pierce, caused serious 
losses in the State of Sao Faulo. (.Moreira. ) In Minas Geraes the weevils were 
very abundant d.uring .the growing season, having been observed for the first 
time in late January at Vicosa. 

CITRUS FRUIT 



The fruit flies Ceratitis capitata Wied. and Anastrepha f rater cuius Wied. 
continued to cause even more losses to citrus this season where no spraying 
was done in Minas Geraes. In the spray plots against the flies, the infesta- 
tion v.as maintained at almost a minimum. The nore susceptible citrus varie- 
ties, unsprayed, dropped many fruits before harvest. The Mediterranean fruit 
fly was reared from a number of pears for the first time during March, 1933, 
at Vicosa. In the State of Sao Paulo, Ceratitis and Anastrepha were less com- 
mon than usual in the citrus proves, especially in the northern part of the 
State. C. capitate showed quite a. preference for the coffee berries in that 
State (C. Moreira.) 

LepidosaPhes beckii Newm. , Hemichionaspis asmdistrae Sign. , and Coccus 
viridis Green were the most common scale insects observed in citrus groves 
during this season. Minas Geraes. 

Scattered infestations of Saissetia oleae Bern, were observed in the 
citrus nursery during May. Later, upon further examination, specimens were 
taken throughout the groves. This was the first occasion we have had to ob- 
serve it on citrus here at Vicosa. A great majority of adult scales were 
found to have been parasitized by two species of Hymenoptera.. No noticeable 
increase in population could be ascertained. 

The black citrus aphid, Toxoptera aurantii Boyer, was far more common this 
year in the school orchards. Considerable damage was done to nursery stock 
ready for shipment. 

Many citrus fruits grov.ing on young trees were badly damaged by Schisto- 
cerca flavofasciata DeG. during April and May. Little destruction occurred in 
the groves on higher elevations. 

Two species of thrips ap-oeared to be quite numerous in citrus this year. 
Although yet unidentified, they constitute major pests in this section. In- 
jury before harvest time was auite noticeable and by the, end of the season the 
percentage of scarred fruits ran very high as compared to other years. 

In December, several 6-year-old citrus trees were killed by larvae of Cra- 
tosomus reidi Kby. in small plantings near Vicosa. Adults are not very often 
encountered in citrus groves in this region. 

Uumerous leafhoppers have been collected from time to time on citrus. 
None of the species have as yet 'oecn identified. 

Larvae of Sibine nesea Stoll, which feed on the foliage of citrus and plum, 
were found for the first time devouring the leaves of castor bean in December. 



-62- 

Macrodactylus suturalis Mann, was found feeding on orange blossoms in the 
Federal District. (C. Moreira. ) ' 

A citrus mite, jiro^aJoly Fhyllocor)tes oleivor u.a Ash'n. , vas responsible for 
the russeting of many fruits. Tiiese mites are generally distributed in Brazil, 
especially in older groves and on trees that receive no treatment vhatsoever. 

APPLE, FEAR, & QUINCE 

The West Indian fruit fly, Anastrenha fraterculus VJied. , destroyed 95 per 
cent of the apples growing in the College orchards during February. 

The scale Aspidiotus lataniae Sign, is the only scale insect observed so 
far on apple in this part of the State. 

The black scale, Saissetia oleae Bern., was found on pear in -September. 

Three quince trees were found lightly infested with the scale Tachardia 
cydoniae Hempel in April. 

Eriosoma lanigerum Hausm. has been encountered in the States of Sao Paulo, 
Rio Grande do Sul, Minas Geraes, and the Federal District. It seems reasonable 
to believe that the parasite Aohelinus mali Hald. has prevented this aphid from 
making further spread in Brazil. (C. Moreira.) 

PEACH 



The San Jose scale, Aspidiotus -pernio iosus Comst., until the present time 
confined to the States of Rio Grande do Sul and Parana, has appeared on peach 
in the State of Rio de Janeiro. (C. Moreira.) 

The white peach scale, Aulacas'ois oentagona Targ., was very common on both 
peach and mulberry. The parasite Prosnaltella berberi How. which now exists in 
Brazil is almost always found parasitizing these scale insects. (C. Moreira.) 

A small infestation of Anurauhi s -oruni co la Za.lt. was found on a dozen peach 
trees during May at Vicosa. This aphid also occurred in Maria de Fe in February. 

Two species of Acanthoderes were very common on the trunks of "peach trees 
during November. 

GRAPE 

The grape phylloxera, Phylloxera vitifoliae Fitch, still remains confined 
in the States of Rio Grande do Sul, Santa Catarira, and a small area in Sao 
Paulo. (C Moreira.) 

A VOCADO 

Coccus hesperidum L. and Saissetia o leae Bern, were observed for the first 
time this year attacking avocado trees in Vicosa. 



-63- 

PIN5APPL5 

Pineapple foliage is commonly infested by Diaspis brome'iiae Bouche through- 
out this part of v 'inas Geraes. 

MISCELLANEOUS FRUIT 

Saissetia hemisJ?,aerica Targ. and S. oleae Bern, are occasionally found in- 
festing various Annonaceae. 

The curculionid H eilj-ous c atagraphus Germ, was taken many times during 
January, August, and November feeding on the foliage of the Annonaceae, Fruta 
de Conde. This borer is responsible for serious losses in several varieties of 
f rui t . 

The whitefly Dialeurodicus cockerelli Quaint, was the most common insect 
observed on the foliage of Arasa. Anastrepha fraterculus T7ied'. did not serious- 
ly injure the fruits from these trees this season. 

Adult cerambycids, Trachyderes succinctus L. and T. striatus Fab., v:ere 
collected many times while feeding on the ripened fruits of a Japanese persim- 
mon. 

The fruit flies, Ceratitis and Anastrepha were taken on Surinam cherry 
during September. 

Adults of Entimus imoerialis Forst. were observed feeding on the foliage 
and fruits of the Brazil nut (cast anna de Para) at Ponte Nova during January. 
(Det. L. L. Buchanan) 

TOMATO 

A tomato vorm, Leuci nodes elegantalis' Guen., was generally present and 
caused some injury to tomato this year but. owing to the small crop no definite 
information could be collected. 

A plant bug, Phthia pi eta Drury, was more common this season in tomato . „ 
plantings. Nymphs and adults destroyed many fruits, thus influencing fungus 
infection during the dry season. 

Two bugs, Arvelius albopunctatus DeG. and Aero sternum bipunctula Stal, 
were collected from tomato during June. (Det. H. G. Barber.) 

A chrysomelid, Diabrotica' soeciosa &em. , very common on a great variety 
of crops, was exceptionally injurious to tomato fruits. The beetles eat out 
cavities in the young fruit. 

SWESTPOTATO 

Nymphs and adults of Corecoris fusca Thunb. were taken while feeding on 
wild swectpotato plants in January. (Det. H. G. Barber. ) 



-64- 

The cweetpotato weevil Euscepes "batatae Waterhouse caused as high: as 14 
per cent losses in the more important varieties of sweetpotato in the College 
plots this season. ' 

IRISH POTATO 

The tobacco leaf -miner . &Jf^.:'^tr-hw~.t'?' operculella Zell., absent during the 
growing season, appeared after harvest, infesting the second growth of Irish 
potato or "suckers" in one planting at the College. This insect has not "been 
observed in potatoes at Vicosa. 

In an Irish potato planting of approximately 5 acres, a species of Pseudo- 
.coccus was found infesting the roots during November. By mid- December the en- 
tire field was infested and serious loss resulted in the final yield. 

Two species of Zpicauta are occasionally found feeding on Irish potatoes 
in Minas Geraes. 

The potato flea beetle, Eoitrix cucumeris Harr., was present throughout 
the latter half of the growing season but was of very, little importance in near- 
by potato fields. 

EGGPLANT 

In January, adults of Phyrdenus mur icons Germ, were taken a number of times 
on eggplant. Larvae were not observed on the roots of the same plants despite 
the fact that careful search was made for them. ... 

A ohrysomelid, Colaspis sp. , is quite a serious pest of eggplant. .Larvae 
feed on the roots, and the adults consume quantities of the foliage, eating 
out large holes, thus weakening the plants to such an extent that they fail to 
produce. 

ONIONS 

The onion thrips, Thrips t abaci Lind. , was very common in onion beds from 
August until October, 1932. 

CA33AGE 

A dipterous leaf-miner, probably Agromyza sp. , was very numerous in cabbage 
and "couve" plantings throughout the season. The same species was reared many 
times from wild mustard. 

The cabbage aphid, Brevicoryne brasnicae L. , was occasionally observed but 
never in sufficient numbers to warrant control measures. 

The diamond back moth, Plutella maculioennis Curtis, was common all year 
attacking preferably "couve" rather than cabbage grown side by side. 

BEANS 



Larvae of Lamprosema indicata Fab. (Det. SF.T.M. Forbes) appeared in March 
and until June caused slight losses in beans. The moths are very numerous at 
lights. Minas Geraes. 






-65- 

A thrips, probably Heliothrros fasciatus Ferg. , is very common in beons 
and other plants, especially during January. 

A species of Spicauta was encountered feeding on the foliage of beans dur- 
ing November. 

MELONS 

Two coccinellids, Emlgchna clandestina Muls. and E. spreta Muls. , are 
generally present in all squash plantings. Both species were observed on 
watermelon foliage during December. 

The cotton aphid, Aphis gossypii G-lov., appeared early in two melon, 
plantings and caused serious injury to the young plants. Control measures 
were necessary. In cucumbers the aphid was not seen in great numbers. 

Diabrotica speciosa G-erm. , D. bivittula K. , and a species of Colaspis often 
cause serious losses in young squash plantings during November and December. 

The melon worm, Diaphania hyalinata L. , was observed for the first time 
feeding on the foliage of pumpkin here in Vicosa during January. D. nitidalis 
Stoll was seen many times at lights but never observed in the field. 

A cecidomyiid, probably Zudiplosis b rasiliensis (Rbs.), infests the fo- 
liage of manioc causing characteristic galls. 

TOBACCO 

The flea beetles Emtrix -parvula Fab. and S. cucumeris Harr. caused serious 
losses to tobacco during April at Vicosa. The infestation this year was the 
worst that has occurred in the past three seasons. 

Larvae of Fhlegethontius sexta Johan. were not able to damage tobacco fo- 
liage to any extent owing to the fact that their natural enemies held them 
well in check. 

Two capsids, Ungytatus spp. , were very abundant but never of any real im- 
portance as tobacco pests. 

A reduvM, Apiomcris lanir-.es Fab. (det. H. G-. Barber), may be seen posing 
on the leaves of tobacco plants during March and April. These bugs are known 
to kill and feed on the honeybee. 

MISCELLANEOU S PLANTS 

Two bamboo scales, Asterolecanium bambusae Bdv. and A. miliar! s Bdv., 
are very common wherever bamboo is grown in this region.

Sevcral young tea trees were found infested with Chrysomphalus aonidum L. 
and Ceroptastes floridenais Comst. during late September. 

A weevil, Pseudopachymerus brasiliensis Thuno. (det. II. S. Barber), was 
found to have destroyed 20 per cent of the seeds of Mucuna in a small lot of 
seed for planting. This species is not verv common at vicosa. 

The West Indian fruit fly, Anastrcnha fraterculus I7ied., is the worst 
insect enemy of the goia"ba fruit. Bone of the other fruit flies have been 
reared from these fruits. 

One small goiaba tree was found badly infested with Ceroplastes grandi s 
Hempel and Aspidiotus lataniae Sign. (Det. A. Hempel.) 

A coccid, Pendularia -pendens Fons. , was observed for the first time on 
the smaller twigs of the jaboticaba tree here at Vicosa during May. Anas- 
t repha fraterculus \7ied. flies were also seen on the fruits of this same tree 
in October at Fonte Nova, Minas Geraes. 

The palm aphid, Ce rat aphis lataniae 3dv., seriously infested several hun- 
dred palms ( Xanthophoeniy. alexandria ) on the school property during August and 
Sej)tember. The infestation was quickly reduced after two applications of kero- 
sene emulsion. 

A weevil, Hadropus albiceris Germ., was. taken many times from the jacaranda 
tree. (Det. L. L. Buchanan.) 

Eggs, larvae, and adults of Psyllobora confluens Fab. , a phytophagous coc- 
cinellid, were taken on the leaves of a "manoeiro" plant in November. This 
cocci nellid is known to feed on the fungus Asper is-oerium carecae and anthrac- 
nose which infest- this fruit. 

Adults of Anastreoha fraterculus Wied. were reared from the seed pods of a 
leguminous plant . Ih^a sp, during March. 

Adults of Fhaedon confinis Stal com"oletely destroyed a small planting of 
crotalaria during January. The beetles are common feeders on a number of plants, 

CORN AND SORGHUM 

The corn aphid, Aphi s maidis Fitch, caused injury to field corn during 
January and February. The infestation was quite severe in about 2 acres of one 
field where many plants were literally covered by the aphids. The aphids were 
also taken in sorghum at the same time. 

The formiga sauva, Atta sexdens L. , continues as one of the worst pests of 
Brazil. County organizations in several localities are already in existence 
doing good service among the farmers. (C. Moreira. ) 



INSECT PEST SURVEY BULLETIN 



Vol. 13 Hay 1, 1933 No 



THE HOPE IMPORTANT RECORDS FOR APRIL, 1933 

During late March and early April cutworms were very troublesome to toma- 
toes and Irish potatoes in southern Mississippi. The outbreak of the western 
army cutworm reported in the last number of the Insect Pest Survey Bulletin 
from Kansas terminated about the third week in April, and during the last week 
in the month moths were emerging in numbers. In one instance during the height 
of the outbreak populations as high as 90 cutworms per square foot were ob- 
served near Manhattan. This species was also troublesome in several localities 
in Montana.. 

Grasshopper eggs examined late in April in North Dakota and Wyoming were 
found to have wintered with very low mortality; 90 per cent survival is re- 
ported from North Dakota and 95 per cent from Wyoming. 

An outbreak of the mormon cricket has developed in eastern Idaho. 

The wirewoTffl Heteroderes Laurent ii Guer. was very troublesome in southern 
Alabama early in the month, and in many patches every kernel of corn was at- 
tacked. 

The vegetable weevil has been found at Clemson College, S.Ci - This is the 
northeast ernmost record for this insect and the first record for this State. 

Heavy rains during the second and third weeks in April had very little ef- 
fect on hibernating chinch bugs in Illinois. The insect also seems to have 
passed the winter successfully in Missouri, Kansas, and parts of Iowa. 

In general apple aphids are decidedly less numerous than usual. The rosy 
apple aphid, however, during the later part of the month developed in trouble- 
some numbers in New York and Virginia. 

The first specimen of the plum curculio was recorded from hibernation in 
eastern Jackson County, Miss., on March 20, at Harriman, Tenn. , on April 6,^ 
and at Newark, Del., on April 10. These insects suffered such, heavy mortality 
in the Port Valley peach district of Georgia that little trouble is anticipated 
from this pest this year. 

Following a very dry March, strawberries in the Chadbourn district of Nor' 
Carolina were very heavily infested with the common red spider.. In some locali- 
ties this infestation was so heavy that no marketable crop was harvested. 

A single egg mass of the gipsy moth has been discovred at Mount Freedom, 
Morris County, N. J. This is the first record in this State since the eradica- 
tion campaign was closed four years ago. 

Heavy infestations of the southern pine beetle have been found in southern 
Pennsylvania, western Maryland, and northern Virginia. This is the most notabis 
outbreak since that of 1893 and is located in the northernmost part oi the range 
of this insect.

this spring as they have been for a number of years, and very little damage 
has been seen or reported. 

Mississippi. K. L. Cockerham (April 10): From March 24 to the present time cut- 
worms have been very bad in Biloxi. Tomato plants and Irish potatoes have been 
severely damaged. 

Kansas. H. B. Hungerford (April 20): Cutworms are very abundant in Baldwin and 
Newton on peonies and other plants. 

H. R. Bryson (April 23): The moths of the western army cutworm, Chorizagrotis 
auxiliaris Grote, were out last week at McPherson and southward to the State 
borders. Injury has ceased, and the worms are going into the pupal stage. 
The damage was confined largely to fall-sown alfalfa, wheat, oats, and vetch. 
Between March 27 and April 17, reports of injury v/ere received from Clonmel, 
Andale, Colwich, Buhler, Herington, Ellsworth, Jamestown, Chautauqua, Frankfortj 
Gypsum, Courtland, Bison, and Hillsboro. Counts made at Manhattan showed a 
population of 45 to the square foot. As many as 90 were taken on 1 square 
foot of soil in a patch of vetch. 

Montana. A. L. Strand (April 20): The army cutworm, C. auxiliaris , has been 

present in winter wheat fields near Portage and Power, Cascade County. Since 
first reported in March they have been covered by 1 to 2 feet of snow. 

ARMY WORM ( Cirphis unfouncta Eaw.) 

Illinois. W. P. Flint (April 19): Very heavy flights of armyworm moths occurred 
in central Illinois on the night of April 9. The flight was apparently ge:::or.rj 

SOUTHERN ARMYWORM ( Prodenia eridania Cram.) 

Florida. J. R. Watson (April 25): On March 11 the young caterpillars of the 
semi-tropical army worm were sent in from Bartow, where they were injuring 
grass in lawns and other plants. 

GRASSHOPPERS (Acrididae) 

North Dakota. J. A. Munro (April 21): Eggs of Camnul a -pellucida Scudd. have been 
received from Renville and Ward Counties for testing. More than 90 per cent o: 



-69- 

them are in hat chat le condition'. The soil 'samples were very heavily infested 
with eggs. 

iVisconsin. C. L. Fluke (April 24): Grasshoppers are reported in Richland County. 
Hatching "began as early as April 12. 

Wyoming. C. L. Corkins (April 19): Egg survival is 95 per cent. Spring is back- 
ward. I do not expect hatching for several weeks. Indications point to more 
or less serious infestations in the Bighorn Basin. 

WHITE GRUBS ( Phyllophaga spp.) 

Connecticut. W. E.'Britton (April 22): Four adults (P. tristis Fab.) were received 
from Willimantic, where this insect was reported as abundant in patches where 
the grass had been killed. Usually we do not consider this as a very destructive 
species. 

Pennsylvania. J. N. Knull (April l) : Reports indicate that many white grubs are 
infected with a fungus, in the area in Perry County where they did considerable 
damage to coniferous plantings in 1932. 

)hio. E. W. Mendenhall (April 24): White grubs are very abundant in southeastern 
counties on strawberry plants. 

Illinois. W. P. Flint (April 19): These insects are now working their way out to 
the surface soil; in the central and northern parts of the State only small 
numbers are yet in the area ordinarily reached in plowing. Mr. Chandler reports 
finding 40 white grubs in 300 square yards ; of earth at Carbondale. These were 
almost equally divided between grubs of Phyllo-pha^a and those of the southern 
June beetle, Cotinis nitida L. 

Wisconsin. C. L. Fluke (April 24): White grubs are moderately abundant in 

Lafayette County. Adults of Brood A are present in considerable numbers but 
have not emerged. 

!owa. H. E. Jaques (April 25): White grubs- show evidence of causing serious 

damage later. Carroll, Jasper, Wright, Palo Alto, Osceola, Buena Vista, Henry, 
Tama, and Union Counties report them as showing up. 

lissouri. L. Haseman (April 24): White grubs are moderately abundant at Columbia. 
Most grubs taken at this time are one-half grown. 

Kansas. K. R. Bryson (April 23): White grubs are moderately abundant at Manhattan, 
and are feeding very close to the surface of the soil. 

WIREWORMS ( Slater idae) 

laine. C. R. Phipps (April 25): Agriotes mane us Say is moderately abundant generally 
over the State. In last season's potato fields the wireworms are at a depth of 
6 to 8 inches. 

/irginia. H. G. Walker (April 26): Wireworms are moderately abundant in some 
potato fields at Norfolk. 



-70- 

Alabama. K. L. Cockerham (April 5): On April 5 Heteroderes lauren tii Guer. was 
found very plentiful in young corn in some plats at Foley. Nearly every 
sprouting kernel had been attacked. Damage seemed to be worse in corn spaced 
3 feet in the rows than in rows where the seed was thickly planted. 

Missouri. L. Haseman (April 24): Wireworms are moderately abundant at Columbia, 
in some sod-land, but not so abundant generally speaking. 

California. E. 0. Essig (April 22): Wireworms are moderately abundant in the 
Delta district. 

A. E. Michelbacher (April 20): Near Rio Vista during the past month a small 
species of wire worm (probably A nchastus cinereipennis Mann.) has caused slight 
damage to sugar beets. A largerspecies (probably Limonius canus Lee.) has 
completely destroyed the sugar-beet stand over a couple of acres of very sandy 
land near Courtland. Both of these places are in the Delta area of the 
Sacramento River. 

JAPANESE BEETLE ( Popillia .japonica Newm.)* 

New Jersey. C. H. Hadley (April 25): During April, larvae of the Japanese beetle 
resumed activity and were in process of moving upward in the soil from their 
hibernating quarters to their usual feeding areas just beneath the ground 
surface. In the older infested districts indications point to some reduction 
in numbers compared with 1932, with, however, some local exceptions. 

. ASIATIC GARDEN BEETLE ( Autoserica castanea Arrow) 

New Jersey. C. H. Hadley (April 25): Grubs of the Asiatic garden beetle are now 
moving up in the soil from their winter hibernating quarters. 

ASIATIC BEETLE (Anomala orientalis Waterh.) 

New York. C. H. Hadley (April 25): The grubs of the oriental beetle are starting 
to return to the upper layer of soil. At Jericho, Nassau County, grubs have 
killed 20 per cent of the plants in a red raspberry bed. Over 50 grubs were 
found around the roots of one plant. 

COMMON RED SPIDER ( Tetranychus telarius L.) 

Mississippi. C. Lyle and assistants (April): Red spiders are very abundant on 
citrus and other plants at Ocean Springs. 

Nebraska. D. B. Whelan (April): Red spiders are quite numerous on gooseberries. 

MORMON CRICKET ( Anabrus simplex Bald.) 

Idaho. W. H. Larrimer (May 2): The outbreak scheduled Ito occur again this year 
in eastern Idaho has materialized according to reports from that State. 

♦Correction. Page 39 - April 1, 1933. State is New Jersey, not Pennsylvania for 
note on Popilla japonica Newm. and Cotinis nitida L.

CEREAL AND FOR AGE-CROP INSECTS 

WHEAT 

HESSIAN ELY ( Phytophaga destructor Say) 

Iowa. C. J. Drake (April): Moderate infestation along the Missouri River, 
especially in Monona County. 

H. E. Jaques (April 25): The Hessian fly is reported from the following 
counties: Warren, Monona, Union, Wright, Henry, Osceola, and Palo Alto. 

Missouri. L. Haseman (April 24): Indications are that the Hessian fly will "be 
serious in central and perhaps southeastern Missouri this spring. 

Kansas. H. B. Hungerford (April 20): The Hessian fly is moderately abundant in 
Lawrence. 

Nebraska. M. H. Swenk (April 20): "V:^ Hessian flies are moderately abundant. 

CHINCH BUG ( Blissu s le ucopterus Say) 

Illinois. W. P. Flint (April 19): There has been no movement as yet from winter 
quarters. Recent examinations by Mr. Bigger show that the heavy rains of the 
past two weeks have had little effect in killing bugs in hibernation. 

Iowa. C. J. Drake (April): Chinch bugs are numerous in 16 counties. ' . 

H. E. Jaques (April 25): Chinch bugs are in evidence in Lee, Osceola, Henry, 
Union, and Carroll Counties. 

Missouri. L. Haseman (April 24): The chinch bugs in central Missouri have been 
moving to wheat and in some fields are mating. Infestation is quite general 
and in some fields heavy. 

Kansas. H. B. Hungerford (April 12): The chinch bug is moderately abundant in 
Douglas County. (April 20) : The chinch bug is moderately abundant in 
Lawrence. 

H. R. Bryson (April 23): It is difficult to form an accurate opinion regarding 
the status of the chinch bug situation at Manhattan at this time. More chinch 
bugs were in hibernation in bunch grass daring the past winter than one year 
ago. It is known that the mortality of the hibernating bugs was very small. 

Nebraska. M. H. Swenk (April 20): The chinch bug is moderately abundant. 

CORN 

CORN EAR WORM ( Heliothis obsoleta Fab . ) 

Alabama. J.'M. Robinson (April 21): Adults are active in Auburn in moderate 
abundance. 



CORN FLEA BEETLE ( Chaetocnema -pulicaria Melsh.) 

North Carolina. C. H. Brannon (April 11): A field of young corn in Scotland 
County was seriously damaged. 



-72- 

ALFALFA 

ALFALFA "WEEVIL ( Hyp era postica Gyll.) 

Nevada. C-. G. Schweis (April 20): The alfalfa weevil is moderately abundant at 
Reno and Fallon. Oviposition has started although the temperature is "below 
normal. 

California. A. S. Michelbacher (April 20): Throughout the infested area there 
ha"s. been an increase in the number of larvae collected. The heaviest infes- 
tations are apparently around Pleasanton. Rather large numbers of the larvae 
have also been collected in the Mies and Tracy a^eas. In the fields which 
have received but little care some damage has been done but for the most part 
it has been very slight. At the present time larvae of all stages of devel- 
opment can be collected. Egg laying is still going on, and adults of the new 
generation have been emerging for some little time. 

ALFALFA WEBWORM ( Loxostege commixtalis Walk.) 

Colorado. G-. M. List (April 25): Moths of the alfalfa webworm began to appear in 
limited numbers in the more southern part of the state early in April. Some 
have been noted flying in the Fort Collins section during the last few days. 
The height of the flight will probably occur about the middle of May. The 
overwintering forms are very numerous in the soil in many sections of the 
eastern half of the state. In some fields the population averages from 2 to 
4 per square foot. 

CLOVER LEAF WEEVIL ( Hyp era punctata Fab.) 

Utah. G. F. Knowlton (March 25): An adult clover leaf weevil was found in 

hibernation under a rock in the foothills east of Logan, about 1 mile from the 
nearest alfalfa field. 

PEA APHID ( Illinois pisi Kalt.) 

Virginia. H. G. Walker (April 26): The pea aphid is becoming very abundant and 
injurious on alfalfa and is beginning to migrate to peas. 

Mississippi. C. Lyle and assistants (April): The pea aphid was first observed 
April 16 at Pascagoula on peas. It is also reported as very abundant on 
English peas at Ocean Springs. (Abstract, J.A.H.) 

Kansas. H. R. Bryson (April 23): The cold, dry weather in Kansas apparently was 
conducive to the development of the pea aphid. Reports of injury to alfalfa 
have come from Newton, Kerington, Cottonwood Falls, and Manhattan. 

California. A. E. Michelbacher (April 20): The pea aphid on alfalfa increased up 
to cutting of the first crop. This pest was very abundant around Vernalis, 
and quite numerous in some fields about Tracy. 

A PLANT BUG ( Thyanta puctiventris Van D.) 

Utah. G. F. Knowlton (April 4): This pentatomid is ..labundant on an alfalfa seed 
farm at Leseret, causing the farmers some concern. ... 



-73- 



SUGASCAM 

SUGARCANE BORER (Diatraea saccharalis Fab.) 

Louisiana. H. A. Jaynes and E. K. Bynum (April 14): While examining sugarcane 
plants during the week of April 7 to 13, we found 10 egg clusters of the 
sugarcane borer and also two stalks of cane with young "borer larvae. The egg 
clusters were not very numerous, as we examined 7,000 feet of cane, "both sides 
of all leaves, and obtained only 10 clusters.

1ST. Y. State Coll. of Agr. News Letter (April): Rosy aphids started to appear 
in the second week of the month and developed rapidly in the Hudson River 
Valley and the Finger Lake district. By April 24, as many as 70 aphids could 
be found in 100 buds. During the last week in the month the apple grain aphid 
( Rhopalosiphum prunifoliae Fitch) was quite scarce throughout the Hudson 
River Valley but in the western part of the State it was quite abundant-. ^By 
the middle of the month the green apple aphid ( Aphis pomi DeG.) was starting 
to hatch in the Lake district, and central New York. (Abstract, J.A.H.) 
P. J. Parrott (April 21): The rosy aphid, the grain and green aphids are 
moderately abundant in western New York.

aphids have been noted. Also the other two species seem to be doing no harm. 

Mississippi. C. Lyle and assistants (April): Fruit aphids have continued un- 
usually scarce throughout the State. On March 30 a very heavy infestation of 
the woolly apple aphid ( Eriosoma lanigerum Hausm. ) was observed on elm trees 
on the property of the School for the Deaf in Jackson. The trees shed a large 
number of leaves owing to this heavy infestation. (Abstract, J.A.H.) 

Oregon. D. C. Mote (April 10): 30 per cent of A. roseus hatched by April 10 in

dant at Morgantown on scattered peach trees. 

Ohio. E. W. Mendenhall (April 24): Where there has been neglect in the dormant 
spray there is an increase in the infestation on fruit trees in central Ohio. 

Wisconsin. E. L. Chambers (April 25): We have made accurate counts of San Jose 
scale survival in a number of sections of the State in search for suitable 
experimental plots and have found in Sheboygan County, the point farthest 
north where San Jose scale has ever been found in Wisconsin, a number of 
small orchards within the city limits which showed 94 per cent dead scales, 
while in Racine County the survival was greater, the percentage being 10 to 
15. 

Iowa. H. E. Jaques (April 25): The San Jose scale is reported as doing serious 
damage in Buena Vista, Tama, Pottawattamie, Palo Alto, Carroll, Clay, Sioux, 
Union, Lyon, Guthrie, and Osceola Counties. 

Missouri. L. Haseman (April 24): In central Missouri on trees where the San Josei 
scale was abundant last fall it does not seem to have survived the winter very 
well . 

Mississippi. C. Lyle and assistants (April): The San Jose scale is from moderate- 
ly to very abundant on a great variety of plants throughout the State. At 
Jackson it was so abundant as to be killing trees in a small orchard. (Abstra 
J.A.H.)

22, 25 to 30 per cent pupae; St. Joseph, April 18, 10 per cent pupae. 

Kansas. H. R. Bryson (April 23): It is estimated in Doniphan County that 
approximately 50 per cent of the overwintering larvae passed the winter 
successfully. Since the infestation was very heavy last year there are strong 
prospects for an outbreak this year. It was not difficult to find larvae 
- under hark scales in mature orchards, 76 larvae having been taken in a few 
hours' search.

EYE-SPOTTED BUDMOTH ( Spilonota ocellana Schiff.) 



New York. N. Y. State Coll. of Agr. News Letter (April): Up to the end of the 
month but little damage was observed throughout the State. A few larvae were

part of the State. The emergence has passed its peak. ■ 

Georgia. 0. I. Snapp (April 25): Eggs are. beginning to hatch at Fort Valley. The i 
first larva of the season (just hatched) was observed on April 15. Twig injurj; 
was evident on April 20. This is about the usual time for the first larvae to 
hatch and therefore the usual number of broods is anticipated this year. The

Illinois. W. P. Flint (April 19): No oriental fruit moth twig injury in southern 
Illinois as yet. 

Tennessee. H. G. Butler (March 31): Pupae were found in the insectary stock at 
Harriman March 15, and today (March 31) 4 adults emerged. This is two weeks 
earlier than the first observed emergence in 1932. (April 11): Eggs were 
found in insectary stock jars on April 10. These are the first eggs observed 
this season. (April 20): Eggs laid April 10 were hatching today (April 20). 
These were the first eggs secured from the insectary stock of moths.

Delaware. L. A. Stearns (April 24): The first emergence from hibernation was 
observed April 10. 

South Carolina. A. Lutken (April 24) : Plum curculios are scarce generally. 
Emergence has been slight. 

Georgia. 0. I. Snapp (April 14): An examination of adult curculios in hibernation 
cages containing bark and Johnson grass reveal a 100 per cent mortality. This 
is attributed to the Unusually cold weather in February which followed a period 
sufficiently warm to cause peach trees to bloom. Jarring records show that 
there are very few curculios in the orchards and the infestation to date is 
much less than that of an average year. A few of the larvae in peach and plum 
are now about 1 week old. (April 20): This insect should not cause much 
damage this year if emergence from hibernation has already been completed. 
Jarring records continue to show a very light infestation in most orchards. 
Temperatures have been below normal, and this may be keeping some individuals 
in hibernation. 

J. B. Gill (April 25): The plum curculio is moderately abundant at Albany on 
peaches and plums, 

W. H. Clarke (April- 6): The first eggs were found in fruits today at Thomas ton 
(April 10) : The first larvae of the season were found today.

New York. N. Y. State Coll. of Agr. News 'Letter (Aprii) : During the first week 
in April the pear psylla began laying eg-rs in the Hudson River Valley. Egg- 
laying, however, continued rather light through the next two weeks. In the 
western part of the State egg-claying was well under way by the middle of the 
month and was heavy during the third week when spraying was started in many 
sections. (Abstract, J.A.H.) 

PEAR THRIPS ( Taeniothri-ps inconsequens Uzel) 

New York. N. Y. State Coll. of Agr. News Letter . (April) : During the first week

Michigan. R. Hutson (April 22): During the month of April we have bred out from 
material collected last summer' A; communis ab . rubicola from raspberry. 



-79- 

De termination has teen confirmed by W. S. Fisher, who informs us that a great 
deal of the dfimage hitherto ascribed to A. ruf icollis in the central and 
southeastern parts of- the State is due to A. communis ab. rubicola . At least, 
since we have bred out the pest and studied the injury, we find that the borings 
of A. communis var. rubicola more nearly resemble the specimens' available from 
the central and southeastern sections of the State than those of A. ruf icollis .

for the State, so far as we know, of this gall-forming cynipid. There were a 
number of thousands of the adults- which emerged from about one-half pint of 
the galls. This is all the more alarming because the blueberry industry 
reaches quite important proportions at South Haven. That is where the new 
varieties are being worked out. The galls came from a wild patch in the vicinit 
of South Haven. ... ..

unusually abundant in many parts of southeastern New York. In 1932 this 
insect caused severe injury to, and occasionally complete defoliation of, 
ornamental and forest trees in southeastern New York; and similar injury, 
in 1933, appears to "be in prospect, at least for parts of the same area. 

CANKER T70RMS (Geometridae) 

North Dakota. J. A. Munro (April 21): Canker worms are moderately abundant 
in Fargo. Moths began to appear April 15.

South Dakota. 'H. C. Severin (April 1): The first moth, female, was found 
April 1 (or 7th - writing indistinct) at Brookings. 

Kansas. H. 3. Hungerford (April 12): Spring canker worms are abundant at 
Lawrence this season. Fall canker worms also are abundant at Lawrence. 

GYPSY MOTH ( Porthetria di spar L. ) 

New Jersey. New York Packer (April 1): After no signs of the gypsy moth had 
been found in New Jersey for four years and the State was considered to be 
free of any infestation of the insect, employees of the State Department of 
Agriculture recently discovered a gyvsy moth egg mass near Mount Freedom, 
in Morris County, the Department has announced. The egg mass found probably 
represents wind dispersion from an undiscovered colony, probably within 
several miles of Mount Freedom, the Department believes. Although it has 
only a skeleton gypsy moth staff, supervisor, and three scouts, it is en- 
deavoring to locate the parent infestation by thoroughly scouting in widen- 
ing circles the area surrounding Mount Freedom. Because of reduced Federal 
appropriations, the Department has to carry on the work without assistance 
from the United States Department of Agriculture. The egg mass was sent 
to the gipsy moth laboratory of the United States Department of Agriculture, 
in Greenfield, Mass. , and was found to be new and viable. 

BAGWORM ( Thyridouteryx ephemeraeformis Haw. ) 

Ohio. E. W. Mendenhall (April 24): According to the number of bags on the 
shade trees, the indications are that the bagworms will be plentiful in the 
vicinity of Columbus and in southwestern counties. Some property owners 
have handpicked them, which will help to diminish the population of bag- 
worms.

OBSCURS SCALE ( Chrysonrohalus obscurus Comst.) 

Ohio. E. W. Mendenhall (April 24): I found the obscure scale quite plentiful 
on shade trees in nurseries about Dayton. The shade trees on which it was 
found were maples, oaks, and some others. 



BEECH 

A CERAMBYCID BEETLE (Xylotrechus guadrimaculatus Hald. ) 

Connecticut. E. P. Felt-. (April 24): A limb pruner, X. guadrimaculatus , was 
found somewhat abundant in a European beech hedge at New Canaan, and also 
on other beeches in the vicinity. In the case of the beech hedge, possi- 
bly 5 per -cent of the branches, were cut off, some of them having a diameter 
of over 2 inches. This insect has also been recorded from alder and birch. 

ELM 

ELM LEAF BEETLE ( Galerucella xanthomelaena Schr. ) 

New York and Connecticut. E. P. Felt (April 24): Elm leaf beetles were found 
hibernating in numbers, presumably in a building, in the Bronx, and this, 
taken in connection with a similar report from Greenwich, Conn., indicates 
that the pests are wintering successfully and may be destructive later. 

A WEEVIL ( Magdalis armi colli s Say) 

South Dakota. H. C. Severin (April 10 ): The elm snout beetle is giving us 
considerable trouble in the eastern third of the State, '.-here it is de- 
stroying the tops of many of our trees. 

Kansas. H. R. Bryson (April 23): Specimens of Calligrapha scalar is Lee. were 
collected at Pratt by S. G. Kelly, Extension Entomologist. These beetles 
were feeding in large numbers on an unknown species of elm. 

ELM CASS BEARER ( Coleophora limosipennella Dup.) 

New York. E. P. Felt (April 25): The elm case bearer was found in very large 
numbers on an elm at Millbrook, some of the partly grown case bearers being 
already on the tips of buds awaiting the appearance of the young leaves. 

OAK 

A CYNIPID ( DisholcasDis persimilis Ashm. ) 

Mississippi. C. Lyle (April 22): On April 8 a correspondent at Darling, Quit 
man County, sent to this office specimens of live oak twigs containing 
galls caused by D. -persimilis . He indicated that live oaks in that vicinity 
showed heavy infestations of these galls. 



-91- 
A CYNIPID ( Dryo -pliant a aguaticae Ashtn. ) 

Mississippi. C. Lyle (April 22): Correspondents at Magee, Simpson County, and 
Meridian, Lauderdale County, recently sent to. this office oak trigs shoring 
very light infestations of galls caused by Dryophanta sp., probably D. agua- 
ticae . 

A'.CEHMBYCID BEETLE ( Fnymatodes t estaceus var. variabilis L.) 

Tennessee. G. K. Bent ley (April): Oak borer very abundant in eastern Tennes- 
see. 

PIES' 

EUROPEAN PIKE SHOOT MOTH ( Rhyacionia buoliana Schlff.) 

New England, New York, and New Jersey. E. P. Felt (April 24): The European 
pine shoot moth continued prevalent in southwestern New England, south- 
eastern Hew York, and northern New Jersey, individual pines being so bad- 
ly infested as to produce stubby masses at the ends of a large proportion 
of the shoots. 

SOUTHERN PINE BEETLE ( Dendroc tonus frontalis Zimm. ) ! 

. - . / 
Middle Atlantic States. R. A. St. George (April 19): For the first time in 
40 years D. frontalis has reappeared in epidemic status within the most 
northern limits of its range. It is known to have infested at least two 
counties in southern Pennsylvania, several localities between V/ashington, 
D. C, and Cumberland, Mds , and Fairfax County, V a . Although several 
species of pines have been attacked, virgin short leaf has probably suf- 
fered most. Examination of samples from several hundred acres of mer- 
chantable pine timber near Fairfax, Va., revealed heavy broods of the beetle 
that have successfully overwintered in the stems of the trees. Woodpeckers 
have worked the mid and upper portions of the trunks quite heavily, proba- 
bly aiding materially in reducing the numbers of the pest. The infested 
trees are believed to have been weakened as a result of the drought which 
has prevailed in this region for the past two years. Combined rith this, 
mild winters have favored insect development. This is regarded as the 
most notable outbreak of this beetle since that of 1893 in this section. 

RED TURPENTINE BEETLE ( Dendroctonus valens Lee. ) 

Pennsylvania. J. N. Knull (April 18): The first adults were observed in 
flight at Hummelstown on April 18.

on raspberries in Fayette County. 

Ohio. S. 17. Mendenhall (April 24): I find rose plants and some blackberry 
plantations in Fairfield County badly infested with the rose scale. It is 
not so hard to control, hut "here the plants are so badly infested it seems 
to be due to neglect.

ECTOPARASITES 

Pennsylvania. Monthly Letter of the Bureau of Entomology, U. S. D. A., Ho. 225 
(January): Ectoparasites of deer in Pennsylvania. ~ Harold S. Peters, 
Takoma Park, Md. , spent December 5 to 7 studying the ectoparasites of deer 
in south-central Pennsylvania, a. continuation of a cooperative study made 
in the deer-hunting seasons of 1930 and 1931. An examination of 19 deer 
yielded 34 Tricholipeurus v irginianus Peters, 4 - Cervophthirius crassicornis 
(Hitzsch), and 28 Dermacent or ni^rolineatu s Packard. Mr. Peters says, "It 
is interesting to note that only one species of biting louse was found, as 
in other parts of the State two species have been found. Ho especially 



-95- 

heavy infestation was observed. But this information does show us that 
there is a sufficient infestation of external parasites to cause severe 
damage should conditions become favorable for a sudden increase. The past 
three years' survey shows that the lice and ticks are found on deer through- 
out the main deer sections of Pennsylvania." T. virgin! anus has been col- 
lected in 13 counties. "This species of biting louse makes up about 90 
per cent of the biting lice on Pennsylvania deer and was undescribed until 
1930." T. -oarallelus (Osborn), another biting louse, has been found in 7 
counties. "This is the so-called 'common deer louse' but really makes up 
only about 10 per cent of the biting lice on Pennsylvania deer;" C. crassi- 
cornis . a sucking louse, generally.': rather rare on eastern deer, was found 
in 7 counties. The tick D. nigrolineatus was found in 9 counties of the 
State. 

HORSE 

BUFFALO SEATS (Simulidae) 

Mississippi. State Plant Board of Mississippi (April 8): Reports reaching 
the Entomology Department indicate that buffalo gnats are present in large 
numbers in the vicinity of Greenvood, and tlia.t livestock are suffering 
from their attacks. Their presence in numbers is attributed locally to 
the rising of the flood waters. Many planters are already burning smudges 
in fields and around barnyards. 

C. Lyle and assistants (April): The outbreak of buffalo gnats, reported in 
a previous number of the Insect Pest Survey Bulletin, has very materially 
subsided, although reports of abundance are still being received from many 
parts of the State. (Abstract, J.A.H. ) 

BOTFLIES ( Gastrophilus spp. ) 

Iowa. Monthly Letter of the Bureau of Entomology, U. S. D. A., No. 225 (January) 
Botfly la.rvae in horses' tongues decrea.se with the advance of winter. — To 
determine "how Late in the winter, in the northern latitudes, horses may 
continue ingestion of botfly (G. intestinalis DeQ. ) larvae issuing from the 
eggs carried by the host after the last of the fly activity," E. F. Knipling, 
Ames, Iowa, made a count of all larvae found in 20 tongues purchased from 
a disposal plant. The following counts in tongues examined on different 
dates show the waning infestation: On December 1, 52 larvae in 5 tongues; 
on December 9, 31 larvae in 3 tongues; on December 10, 114 larvae- in 2 
tongues; on December 13, 63 larvae in 3 tongues; n December 17, 23 larvae 
in 5 tongues; and on December 31, 7 larvae in 2 tongues. The stomachs 
and duodena of 8 of these horses were examined a.nd following are the find- 
ings: 938 G. nasal is L. in the duodena; 603 G. intestinalis DeG. in the 
stomachs; 1 G. haemorrhoidalis L. in a stomach."

received from Morgantown, Huntington, and other points. 

Ohio. E. 'J. Mendenhall (April 24): Complaints have come in concerning ter- 
mites working their way through cellars and. in foundations of "buildings 
in Columbus, and found doing damage in greenhouses in Dayton. If not de- 
stroyed, they may do considerable damage. 

Illinois. J. H. Bigger (April 17): Termites very abundant April 15. They 
were seen swarming March 18 at Jacksonville. I have examined 8 nro"oerties 
in the last few weeks. 

Kentucky. ',7. A. Price (April 24): During the past three weeks, April 3 to 
24, winged termites have been extant and inquiries have been received from 
all sections of the State. 

Iowa. C. J. Drake (April): Termites have been increasing in numbers in Iowa

and in. Des Moines. 

Kansas. H. R. Bryson (April 23): April 8, termites, were discovered doing 
extensive damage to maple floors and- casings of doors in a modern grade 
building at Manhattan. This was a wood:n floor laid on cement. Stakes 
driven into the ground, making contact with the joists, furnished a means 
of connection between the floor and the groiuid. It is estimated that 
around $5,000 loss has been incurred. (April 15): Termites were reported 
injuring a dwelling at Atchison. Either termite injury is on the increase 
or people have become interested to such an extent as to look for it. 
Probably both conditions are true.

that swarms of these insects are around their yard and in their house and 
.other buildings. . They have tried every way. that they know of to get rid of 
them in the house but do not have any success. ***This is the first year 
that these insects hove appeared there. A residence just across the road 
from them is. not bothered, with them at all. These people are very. clean and 
their premises are kept well cleaned up. They do not have any cattle yards 
or barns near the house. They did get some soil from a water hole to fill in 
a place that blowed out in their yard and they thought that these bugs might 
have come from that soil although the party living across the road from them 
also got some of this same soil and does not have any of these bugs around.

was present on Casuarina equisetifolia L. 

Cerotoma rogersi Jac. ? was taken on Phaseolus vulgaris L. August 31, 1932. 
(Det. H. S. Barber.) 

Spitrix fuscata Jac.-Duv. was taken on muscadine grape March 22 and was an 
important pest on soybean March 13. During March this was a serious pest on the 
foliage of tomato. 

Halticns canus Dist. was reported during March on wheat and on March 14 on 
soybean. 

Guisaro ( Psidiura molle Bertol.). The weevil Attelabus ( Xestolabu s) 
conicollis Sharp eats the leaves. I took it in San Pedro de Montes de Oca in 
November 1932, and in El Cacao in January 1932. (Det. L. L. Buchanan.) 

November 12 to December 18, the weevil G eraeus lentiginosus Boh. was 
apparently harmful in the flowers of avocado. (Det. L. L. Buchanan.) 

November 12 to December 13 the beetle Su-.roctus (? subdeletus Bates) is 
usually found between the leaves of avocado that have been webbed together by 
caterpillars. (Det. L. L. Buchanan.) 

November 12 to December 18 the beetle Crytorhopalum sp. is usually found 
between the leaves of avocado that have been webbed together by caterpillars. 
(Det. E. S. Barber.) 

DIPT2HA 

During March Toxotrypana curvicauda Gerst. was very harmful on papaya. 
This insect destroys 100 per cent of the fruit. 

LEPIDOPISRA 

Eggs, larvae, and pupae of the butterfly Agraulis p oeyi Butl. were present 
on grandilla ( Passiflora li^laris A. Juss.). This is an important pest. March

INSECT PEST SURVEY BULLETIN 



Vol. 13 June 1, 1933 No. 4 

THE MORE IMPORTANT RECORDS FOR MAY, 1933 

Outbreaks of the Mormon cricket are reported from parts of Idaho, Montana, 
and Washington. 

Cutworms were reported from practically the entire country as doing the 
usual'-- «t) ring damage. 

The chinch hug appeared in unusually heavy numbers from central Missouri to 
northeastern and central Oklahoma. In the more eastern part of the chinch hug 
"belt fi^orn Ohio to Illinois very heavy rains during May materially reduced the 
numbers. There probably will be some trouble north of the normal range; as these 
insects seem to have passed the winter very successfully in Minnesota, Iowa, and 
South Dakota. 

The corn ear worm appeared in destructive numbers over the Southern States 
from North Carolina to Florida and Mississippi. Over much of this territory it is 
badly damaging tomatoes and corn, and in North Carolina it is destroying half- 
grown peaches. To a lesser degree it is damaging a wide variety of crops. 

Fruit aphid s continued to be quite generally scarce over the greater part of 
the country. The rosy apple aphid, however, v/as: occasioning some concern in the 
South Atlantic and South-Central States. 

The eastern tent caterpillar was generally prevalent from Maine to Maryland, 
defoliating roadside trees and neglected orchards. 

The warm weather in May resulted in heavy emergence of the plum curculio in 
the Middle Atlantic States. In the Southeastern States infestation was generally 
light . 

The Mexican bean beetle has been found at Monticello, Fla. , which is the 
first record for this State. It has elso been found in southern Mississippi. 
These records are of particular interest, as this insect has made practically no 
advance southward since its original introduction into northern Alabama in 1919. 

The bean leaf beetle was generally damaging beans in the South Atlantic and 
South Central States westward to Texas. 

Heavy damage to alfalfa by the pea aphid was reported from Maryland to Kansas. 
Similar reports were received from the Pacific Coast. 

The tobacco flea beetle was generally prevalent from Virginia and North Caro- 
lina westward to Kentucky and Tennessee. 

An outbreak of the Douglas fir caterpillar was reported from the Lake Tahoe 
district in Nevada. The last outbreak of this insect in this district was re- 
recorded 5 years ago. 

Recent surveys in Connecticut and New York. State, indicate that the^ European 
pine shoot moth has increased in abundance and in some reforested areas it is a 
serious factor.

&ENER-A.L FEEDERS 

GRASSHOPPERS (Ac ridi dae ) 

Michigan. R. Hutson (May 22): Grasshoppers are moderately abundant. Hatching 
in some localities. 

Minnesota. A. G. Raggles and assistants (May): Not more than 1 per cent of the 
grasshoppers had hatched in the Red River Valley up to May 23. (Abstract, 
J.A.H.) 

North Dakota. J. A. Munro (May 20): Grasshoppers were reported moderately abun- 
dant in pass County May 19. We looked over some territory southwest of Par- 
go and found the young hoppers hatching. 

South Dakota. H. C. Severin (April 26): No hatching as yet. (May 15): Eggs 
of Melanoplus bivittatus Say have begun to hatch. 

Wyoming. C. L. Corkins (May 10): Grasshoppers are hatching generally over 
northern Wyoming. Indications are for more or less serious outbreaks some- 
what of a localized nature throughout the Bighorn Basin and in Sheridan 
County. 

Texas. P. L. Thomas (April 28): Grasshoppers are very abundant along rail- 
roads and in pastures in Brazos and Burleson Counties. 

Utah. G. P. Knowlton (May 22): Grasshoppers continue hatching in various parts 
of northern Utah, but up to date no serious outbreaks have been observed or 
reported. Nymphs were most abundant in the Grant svi lie-Dolomite areas of 
Tooele County. Melano-plus sp. are emerging in small numbers at Lakepoint 
and Dolomite in Tooele County and at Lamp in Box Elder County. 

A CAMEL CRICKET ( Daihinia brevipes Hald.) 

Oklahoma. C. P. Stiles (May 23): The California camel back cricket is appear- 
ing in large numbers in Roger Mills and Harmon Counties. Many of the garden- 
ers say they are feeding on vegetation, but so far I have been unable to 
prove this. 

MORMON CRICKET (Anabrus simplex Hald.) 

Montana. A. L. Strand, (May 20): An outbreak has developed in the east end 
of Carbon County where the insect occurred last season. An area of about 
10 square miles is affected. Bands of young crickets (3-4 instars) are 
working down into cultivated crops from the higher range land. 

Washington. L. P. Rockwood and T. R. Chamberlin (May 6): After considerable ex- 
ploration of the Sand Hills northeast of Pasco, we find that Mormon crickets 
are quite abundant over most of an area of at least 10 square miles of range 
land. They appear to hove originated on the south sides of the higher ridges. 
The crickets were in the 4th, 5th, and 6th stages, mostly 5th. 



-105- 

CUTWORMS (Noctuidae) 

Massachusetts. A. I. Bourne (May 25): There is already considerable evidence 
of the presence of cutworms, hut as yet no indication of their relative abun- 
dance as compared with other years. 

Connecticut. W. E. Britton (May 24): Injury to asparagus (10-15 per -.cent) at 
Daniel son, Brooklyn, Canterbury, and Wauregan, May 17, and to cabbage and 
onion (10 per cent) at Windsor Locks May 19, was reported. Also many tele- 
phone inquiries have come to the office regarding cutworms on various garden 
plants. Most of these are local or within New Haven County. 

New York. N. Y. State Coll. of Agr. News Letter (May 22): Cutworms are very 
numerous-- and causing considerable injury in the eastern part of Suffolk 
County. 

Georgia. C. H. Alden (May 19): Cutworms are very abundant in vegetable gardens 
at Cornelia. 

Michigan. R. Hut son (May 22): Cutworms are very abundant. 

Minnesota. A. G. Buggies and assistants (May): Cutworms are generally abun- 
dant throughout the State. (Abstract, J.A.H. ) 

South Dakota. H. C. Sever in._ (May 20): The army cutworm Chori^agrptis. auxilj,- 
aris^ Grote is abundant and destroying small grain in the western half of the 
State. Many complaints are coming in from many sections of the State. Worms 
are moving into grain fields from surrounding pasture land, also from aban- 
doned fields, and are cutting off grain just beneath the surface of the 
ground in Fukwana. 

Missouri. L. Haseman (May 23): Cutworms are very abundant over much of the 
State. At Columbia the variegated cutworm ( Lycophotia margaritosa s aucia 
Hon.) seems to be most important. 

Kansas. H. R. Bryson (May 25): The moths of the army cutworm have been out 

since May 1. They are so numerous that they have become a nuisance in dwell- 
ings. Efforts to find the eggs of these moths apparently confirm the re- 
sults of previous studies made with this insect that the first moths do not 
deposit eggs. Pupae retained for rearing purposes have not emerged. 

Tennessee. G. M. Bentley (May): L. margaritosa saucia and Agrotis ypsilon 
Rott. are very abundant in Knox County. 

Mississippi. C. Lyle (May 24): Specimens of L. margaritosa saucia were col- 
lected" at Clarksdale, Coahoma County, on May 8, and. sent to this office 
with the report that they were severely injuring bur clover, cotton, and 
other plants. A correspondent at Neshoba, Neshoba County, sent us specimens 
on May 10 with a report that they had caused severe injury to a 10-acre cot- 
ton field, one acre of which had to be replanted. Medium injury by this 
snecies to potatoes and other vegetables was reported from Guntown, Lee Coun 
ty, on May 3. A heavy- infestation on alfalfa at Leland, Washington County, 



-106- 



was reported early in May. This species is Moderately abundant on cotton at 
Meridian. The greasy cutworm (A. ypsilon ) is scarce in fiast Jackson Countv, 
and moderately abundant in Yalobusha,. Grenada, and Montgomery Counties, li is 
also ^ scarce at Kosciusko., and moderately abundant at Ocean Springs, Monroe, and 
Wiggxns, and very abundant in gardens and one cotton field in Roblnsonville. 
leltia gladiaria Morr. is scarce on onions at Kosciusko. 

Nebraska. ^ U. H. Swenk (April 20 to May 20): A report was received the last week 
in April from a Jefferson County correspondent stating thatori field of alfalfa 
that had been planted last fall was damaged to the extent of about 50 per 
cent by C. auxiliaris. 



Arkansas. D. Isely (May 22): At present there is an outbreak of the variegated 
cutworm in the northern part of the State, apparently originating in alfalfa 
and bur clover. 



Oklahoma. C. E. Sanborn (April 25): L. margaritosa saucia was very abundant 
in northwest- central Oklahoma during February and March. Cutworms are 
moderately abundant in gardens. 






Texas. J. N. Honey (March 25): Cutworms are attacking all crops planted, name- 
ly tomato, pepper, bean, and watermelon. Heavy abundance. 

R. X. Fletcher (May 2): Injury by Prodenia ornithogalli Guen. was noticed 
scattered over 300 or 400 acres in Brazos County, although injury is not 
severe. 

F. L. Thomas (April 28): Cutworms are scarce. Very few complaints received 
as. yet from any part of the State, except Galveston County. 

New Mexico. J. R. Eyer (April 21): Euxoa sp. are extremely abundant and de- 
structive to alfalfa and all leafy vegetables in Dona Ana and Hidalgo Coun- 
ties. 

Montana. A. L. Strand (May 20): The pale western cutworm ( Porosagrotis ortho- 
g. onj - a Morr.) is much reduced in numbers from last year. Infestations of 
about one to the square yard occur this sea,son, whereas in the same places 
m 1932 heavy damage to crops occurred. The army cutworm (C_. auxiliaris ) 
has been present in Gallatin, Cascade, and Yellowstone Counties but the 
amount of damage has not been large. 

ARMYWORM ( Cirphis unipuncta Haw. ) 

Maryland. W. H. Larrimer (May 29): Armyworm .outbreak at Pearson, '.St. Marys'*' ,; 
Co -ant y, in small grain. 

Virginia. C. R. Willey (May 22): Specimens were received from James City Coun- 
ty,; May 16, with the report that they were appearing in numbers, and cross- 
ing road, and moving from field to field. Many were parasitized by a tachi- 
nid. 

WHITE GRUBS ( Phyllophaga spp. ) 

New Hampshire. L. C. Glover (May 24): Two specimens were taken May 7. On the 
night of May 23 I took 113; it was a warm night. One other night I took 74. 



-107- 

Massachusetts. A. I. Bourne (May 25): The first May beetles were observed 
in Amherst the night of May 5-6. These have since become abundant. 

Connecticut. W. 3. Britton (May 24): In one case adults of P. tristis gab. 
were feeding on bean foliage at New Haven. 

Pennsylvania. T. L. Guy ton (April 28): White grubs P. futilis Lee. and P. 
fervida Fab. are very abundant in the Harrisburg vicinity. (May 22): 
Adult's ■•$. e very abundant in central Pennsylvania. 

Maryland. S. 11. Cory (May 19): Phyllophaga spp. are quite abundant around 
College Parlt, and reports of injury have been received from Baltimore 
County. Blackberries and raspberries in Marlboro have been injured. 

Virginia. W. J. Schoene (May 26): Complaints have been received from Giles 
and Pulaski Counties of injury to shade trees by May beetles. It has 
been reported that the foliage on some trees has been seriously injured. 
C. R. Willey (May 22): Phyllophaga damaged permanent bluegrass pasture 
last summer at Middlebrook, August County. Grubs and adults were dug up 
May 10. Adults are defoliating nut trees near Petersburg, roses in and around 
Richmond, raspberries near Norfolk, and ornamental cherries at Bristol. 

Qf 

Georgia. H. S. Adair (April 26): Considerable evidence/ feeding has been ob- 
served in pecan orchards in the vicinity of Albany, especially in orchards 
which have received little or no cultivation during the past year. 

Ohio. T. H. Parks (May 22): May beetles are more abundant than usual in 
Columbus. 

Illinois. J. H. Bigger (May 13): White grubs are very abundant in western 
Illinois; recent survey shows larvae more abundant than in 1930. 

Kentucky. W. A. Price (Fay 24):' Adults of P. fusca 5Voel. and P. gibbosa. Burm. 

h have been abundant in the vicinity of Lexington during the past 3 weeks. 

Reports indicate that while grubs are abundant in other places in the State, 
especially at Muldraugh, where they were feeding on the foliage of apple 
trees. 

Wisconsin. C. L. Fluke (May 24): White grubs are very abundant and are now ■ 
moving up to the surface layer. 

Minnesota. A. G. Ruggles and assistants (May): White -grubs are generally 
prevalent throughout the State and reported as very abundant from Houston 
County. (Abstract, J.A.H. ) 

Iowa. H. E. Jaques (May): White grubs are very abundant in Osceola, Monroe, 
Black Hawk, Allamakee, and Clayton Counties. They are moderately abun- 
dant in Sioux, O'Brien, Buena Vista, Cass, Montgomery, Pocahontas, Union, 
Jasper, Poweshiek, Keokuk, Van Bur en,- Buchanan, Louisa, and Lee Counties. 

Nebraska. M. H. Swenk (May 20): White grubs were reported doing damage in 
Seward and Sherman Counties during the last month. They were working in 
a lawn in Sherman County and were eating the roots of chrysanthemums and 
delphiniums in Seward County. 



-108r 

Mississippi. C. Lyle (May 33-): On April 29 a correspondent at New Al"bany, 
Union County, reported that May beetles (P, bipartita Horn) bad severely 
in jured 'pecan trees. May beetles have been very abundant during the past 
several weeks, attacking pecans, roses, and other tender growth. .'They 
were doing serious damage to roses in Hinds County on April 28. 

JAPANESE BEETLE (F^pjJJLia japonica Newm. ) 

New York. C. H. Hadley (May 23): The heaviest infestation in New York, which 

is at Long Island City, shows this spring a marked decrease in turf injury 

due to treatment of the turf in the large Community Courts. Many of the 

small private lawns still show grub injury. The heavy part of this infesta- 
tion covers about 10 city blocks. 

Pennsylvania. C. K. Hadley (May 23): Field surveys in the New Jersey- Pennsyl- 
vania area in May show larvae congregated near the surface of the ground and 
actively feeding. In general, in the older infestations a decrease in num- 
bers is indicated as compared with the same time in 1932, but in more re- 
cently infested sections the usual increase has been experienced. A consid- 
erably-greater proportion of the grubs occur at this time in the earlier 
stages of growth than was the case a year ago. 

ASIATIC BEETLE (Anomala orientalis Waterh. ) 

Connecticut. W. E. Britton (May 24): Larvae ascended to the surface of the 
ground earlier than in some other seasons. Injury to untreated lawns is 
being reported every day. 

New York. C. H. Hadley (May 23): The infestation in meadowland at Jericho, 
which was first observed in 1931, has become serious enough so that appro xi"* 
mately half an acre of turf is now ruined and extensive plots without a 
living plant are not uncommon in this area. 

ASIATIC GARDEN BEETLE ( Autoserica castanea Arrow) 

New York. C. H. Hadley (May 23): The grubs are more numerous on Long Island 
than they were a year ago. 

Pennsylvania. C. H. Hadley (May 23): A new and quite heavy infestation has 
been found in the Laurel Kill Cemetery in Philadelphia. 

COMMON BSD SPIDER- ( Tetranychus telarius L. ) 

Mississippi. C. Lyle and assistants (May): The red spider is very abundant on 
strawberry and ornamentals. It is very abundant on plants in general at 
Ocean Springs. There is a heavy infestation on Samellia japonica in the 
vicinity of Pascagoula. Injury to various ornamental plants has been re- 
ported recently from Caledonia and Columbus, Lowndes County, Belzoni, Hum- 
phreys County, and Quitman, Clark County. The correspondent at Caledonia 
indicated that the infestation was very heavy, the arborvitae plant being 
almost completely enclosed in the webs. 



-109- 

CEREAL AND F01AGE-CR0F INSECTS 

WHEAT 

CHINCH BUG ( Blissus leucoptcrus Say) 

Illinois. 17. P. Flint (May 20): Hay thus far has been very rainy, with rains 
of the heavy shower type occurring in all parts of the State. The rain- 
fall is considerably above normal for this month. These rains have had a 
very unfavorable effect on chinch bugs since they left their winter quarters 
and have greatly reduced their numbers. 

Minnesota. A. G. Ruggles (May 23): Chinch bugs came through the winter in 
good shape. They are active around Lake City and Red Wing. 

Iowa. H. E. Jaques (May): The chinch bug is very abundant in Ringgold County 
and moderately abundant in Palo Alto, Van Buren, Henry, and Lee Counties. 

South Dakota. H. C. Severin (April 26): The chinch bug is scarce. 

Missouri. L. Haseraan (May 23): Recent flights of chinch bugs to wheat have 
brought alarming numbers into the crop over much of central and northern 
Missouri. 

Kansas. H. B. Hungerford (May 11): Chinch bugs are unusually abundant at 

Lawrence for this time of year. They survived the winter in large numbers. 
H. R. Bryson (May 25): A heavy flight of chinch bugs occurred at Manhattan 
on April 29 and May 8. On May 1 the adult bugs were sufficiently numerous 
to cause considerable injury to spring wheat and barley in an experimental 
nursery. Eggs were found in the field May 5 at Manhattan, but no young 
bugs have been found at this writing. However, .young bugs are present in 
fields in southern Kansas. Several reports of adults causing injury feed- 
ing at the base of corn plants have been received. At Alma and at Manhat- 
tan eggs' were found at the base of corn plants. The adults also were re- 
ported injuring barley at Calista, and numerous at Argonia. Chinch bugs 
are more numerous at Manhattan this spring than they have been for several 
years. 

Oklahoma. C. E. Sanborn (May 23): Chinch bugs are very abundant in the north- 
eastern and central parts of the State. Young are now hatching. 
C. F. Stiles (May 23): No doubt we have the worst outbreak we have had in 
the past 15 years. All of the central and northeastern part of the State 
is heavily infested; the infestation centers around Creek County. It is 
almost impossible -to examine any field without finding the bugs in large 
numbers. In some instances corn, is heavily infested, there being as many 
as 50 bugs on a plant. At this time the bugs are depositing eggs and a 
few have already hatched. Some oat fields have already been plowed up. 

Texas. R. X.' Fletcher (April 27): This insect is abundant throughout a corn- 
field near College Station, but injury is not yet apparent. Corn is 12 to 
15 inches high. 



-110- 
HESSIAN FLY ( Phytophaga destructor Say) 

Kansas.. H. R. Bryson (May 25): The Hessian fly was a factor in the winter 

killing of wheat by weakening the plants, making them less resistant to low 
temperature. The fly was especially injurious in Russell County, where 
many fields were killed 80 to 100 per cent. The spring "brood of fly at Man- 
hattan is not as heavy as might have' "been expected, judging from the fall 
infestation. Parasites appear to have "been a factor since large numbers 
of them nave been found. 

CORN 

CORN EAR WORM ( Heliothis obsoleta Fab. ) 

North Carolina. R. W. Leiby (May 20): Larvae of what is regarded as this moth 
are reported as burrowing in and destroying half^grown peaches of the Car- 
men and Early Rose varieties in a few commercial orchards near Candor. 
The larvae apparently transferred their activities to peach fruit when 
vetch grown in the orchards was plowed under. 

Florida. E. U. Berger and G. B. Merrill (May 23): The corn ear worm is very 
abundant at Gainesville; injury is unusually severe in some early plantings. 

Alabama. J. M. Robinson (May 20): The corn ear worm is moderately abundant on 
tomato at Brewton and Do then, and moderately abundant at Auburn. . 

Kansas. H. R. Bryson (May 25): First moths of corn ear worm were taken at 
light on May 18. 

Arkansas. D. Isely (May 22): The corn ear worm is moderately abundant on al- 
falfa and vetch. 

P. D. Sanders (May 24): Young larvae of the corn ear worm were feeding on 
the foliage of tomato plants in the fields and on the more mature plants, 
where fruits had formed; were tunneling into them at Nashville. There are 
approximately 150 acres of early tomatoes planted in this section for ship- 
ment to northern markets. Damage to the crop set is serious. 

Louisiana. C. F. Smith and P. K. Harrison (April 27): The larvae of Heliothis j 



which were probably largely or wholly obsoleta . were unusually abundant at 
Baton Rouge and outlying vicinities during April. Crops observed infested 
included cabbage, strawberry (ripening fruit), '-corn, tomato, soybean, 
broad bean, and alfalfa. The most severely infested corn and soybeans 
were growing on land following winter vetch and were planted the same day 
(March 27) the vetch was plowed under- 

... 
Mississippi. C. Lyle and assistants (May): The corn ear worm was causing sevei 

damage to sweet corn in east Jackson County. It was also recorded from 

Copiah, Stone, Forrest, and Rankin Counties, where it was damaging tomatoes, 

In. Rankin County the damage to tomatoes was unusually severe. On. many 

i plants every fruit was infested. (Abstract, J.A.H. ) 

Texas. F. L. Thomas (April 28): Eggs of the corn ear worm have been more abun 
dant this year in Brazos County in corn and alfalfa than they were 1932. 



-111- 

SOUTHERN CORiT STALK : BORER ( Diatraea crambidoides Grote) 

South Carolina. 0. L. Cartwfight (May 22):' Adults arc emerging in numbers at 
Clemson College. 

COM BILLBUGS ( Calendra spp. ) 

South Carolina. 0. L. Cartwright (May 22): Corn billbugs (C. cariosus Oliv.) 
are causing much injury at Florence. 

Florida. J. R. Watson (May 26): The billbug is causing considerable damage to 
corn in various parts of the State, mostly northern counties. 

Alabama. J. M. Robinson (May 20): Corn billbugs are abundant on corn at One- 
onta and Troy. 

SPOTTED CUCUMBER EEETLE ( Piabrotica duodecimpunctata Fab. ) 

Georgia. 0. I. Snapp. .(May 18): Young cucumbers at -Fort Valley have been badly 
damaged. 

Kansas. H. R. Bryson (May 25): The first adults of the year were seen on May 
10. They are quite numerous at Manhattan in alfalfa and in clumps of vol- 
unteer corn. 

Louisiana. C. E. Smith and P. K. Harrison (April 27): At Baton Rouge corn 
has received from slight to very severe damage by the larva. 'The injury 
was especially severe, amounting to 80 per cent or more of the stand, to 
corn planted March 27 on land following winter vetch which was plowed under 
immediately preceding the planting of the corn. The major portion of the 
injury occurred during the period from April 8 to 20, and some is still 
in progress. The first young spring-brood beetles were observed in the 
field at Baton Rouge on April 12. 

Texas. P. K. t g^etch^- .(April 27): Earliest planted corn was very seriously 
injured at /College- Station. 

ALFALFA 

ALFALFA v7EEVIL ( Hyp era postica Gyll. ) 

California. A. E. Michelbacher (May 19): The alfalfa weevil is very abundant 
in the Pleasanton area. Count jp- of several hundred (300 to 800) are being 
taken per 100 sweeps on the second crop, which is from one-quarter to one- 
half grown. In the Niles area the weevil can be collected with ease and 
the number of larvae and adults taken per 100 sweeps ranges around 100. 
In the Tracy area, as a general thing, only a few individuals can be col- 
lected per 100 sweeps. Of the adults collected in all three regions, the 
greatest percentage are of the spring generation. Larvae in all stages may 
be found in the fields at the present time. 






"GRASS 
. A SOD VIEB'.TORM - ( Crambus sp.) ■■• 

Nebraska. M. H. Swcnk (April 20 to. May 20): Injury to a lawn by sod wcbworms 
was reported frtim Scotts Bluff "County the second week in May. 

SUGARCANE 

SUGARCANE BEETLE ( Sucthcola rugiceps Lee. ) 

Alabama.. J. M. Robinson (May 20): The sugarcane beetle is moderately abundant 
on sugarcane at Frisco City and Elmore, and on corn at Excel and Anniston. 

Louisiana. VI. E. Hinds (April 28): Sugarcane beetles appear to be unusually 

widely distributed and are doing considerable damage. Egg laying began aboui| 
the first week of April and newly hatched L?.rvae were found in the field the 
middle of April. f 

J. T .7. Ingram (May 22): The sugarcane beetle began attacking young cane shoot 
during the latter part of March. Injury reached the maximum during the lat- 
ter part of April and the first part of May, and has been decreasing since 
that time. VThile injury can be found throughout the State, the major in- 
jury, as in past years, has occurred in St; Mary, St. Martin, Lafayette, and 
Iberia Parishes. Large areas have had over 25 per cent of the plants killed 
Injury is heavier than it was in 1932 but not so heavy as it was in 1931. 

Mississippi. C. Lyle and assistants (May): This insect was recorded severely i 
juring corn in the vicinity of Hattiesburg and Utica during the latter part 
of the month. (Abstract, J.A.H. ) 



SUGARCANE ROOTSTOCK 77EEVIL ( Anacentrinus subnudus Buchanan) 

Louisiana. 1. E. Hinds (April 28): Sugarcane root-stock weevils occurring in 
stubble cane in Lafayette Farish appear to be a factor in the poor stands of 
cane vrhichare being secured on some areas of well drained soil, as reported 
by Mr. C. 3, Gouaux. 

YIIREVIORMS (Elat eri dae ) 

Florida. T. E. Holloway (May 18): A correspondent reports that wireworms are in 

juring sugarcane in the Everglades. One 40-acre field shows a loss of 50 per 

cent. Replantings have been necessary to procure 'a stand at the State Experij 
ment Station. 

SUGARCANE BORER (Dia'traea saccharalis Fab. ) 

Florida. T. E. Holloway (May 18): Reports from reliable observers in the Ever- 
glades indicate that great damage is being done by the sugarcane borer. 

Louisiana.. VI. E. Hinds (April 28): Sugarcane borer moths began emerging about 
April 1 at Baton Rouge, and somewhat earlier, nrobably about March 20 in 
southern Louisiana. Eggs were first found April 6 at Baton Rouge. Among 
about 1,500 borer eggs collected to April 17 no Tricho gramma parasitism was 
found and no Tricho gramma in some 800 Lepido^terous eggs of other species up 
to that date. 

T. E. Holloway (May 18): The sugarcane borer is slow in reaching harmful 
numbers this year. 

Mississippi. T. E. Holloway and VJ. E. Haley (May 18): No indication of the 
presence of the sugarcane borer was found in an inspection of cane fields 
along the Mississippi coast.

FRUIT INSECTS 

FALL WS3W0EM ( Hyphantria cunea Drury) . . ■ 

Georgia. J. B. Gill (May 25): The first brood of the fall webworm is unusually 
heavy and is destroying much foliage in pecan orchards of south Georgia. The 
insect is also common on persimmon, sweet gum and other trees along the edge 
of woodlands. 

Ohio. T. K. Parks (May 12): Moths were "brought to the office with the statement 
that they were present in a "basement and coming into the living rooms of a 
dwelling house at Columbus. Upon inquiry it was learned that elm trees in the 
yard were badly infested last summer. These probably crawled into the "basement 
to pupate. Emergence was somewhat earlier than would be expected out of doors. 

Mississippi. C. Lyle and assistants (May): The fall webworm was first observed 
on gum trees in the vicinity of Lucedale, George County, on May 18. 

A SCARABAEID ( Hoplia trifasciata Say) 

Massachusetts. A. I. Bourne (May 25) : We received collections from Hampden County 
in the western part of the State and from Bristol County in the eastern part. 
These beetles were found in large numbers feeding on foliage of various fruit 
trees. It is not uncommon to find them present on foliage of fruit trees, "but 
we have seldom had complaints of their presence there in such abundance. 

APPLE 



APHIDS (Aphiidae) 

Massachusetts. A. I, Bourne (April 27): We found the apple aphid ( Aphis pomi BeG.) 
first making its appearance about the 18th to the 20th of the month. Thus 
far throughout the. State there has been little evidence of plant lice. Colonies 
that we have observed have been for the most part the gsain aphid, Rhopalosiphum 
prunifoliae Pitch, and in general, wherever there have been colonies in an 
orchard, various species of lady beetles have been attracted and are disposing 
of them rapidly. 

New York. N. Y. State Coll. of Agr. News Letter (May): Throughout May aphids were 
in general very scarce. Both green, A. pomi , and apple grain aphids, R. 
prunifoliae .were outnumbered by the rosy apple aphid, Anuraphis roseus Baker, 
over the greater part of the State. Hatching of the rosy apple aphid was 
practically completed by the last week in April in the western half of the 
State. By the middle of the month the rosy apple aphids had developed quite 
a population, however, and in some parts of the State appeared threatening. 
(Abstract, J.A.H.) 

ROSY APPLE APHID ( Anuraphis roseus Baker) 

Maryland. E. N. Cory (May 22): The rosy apple aphid is very abundant. 

Virginia. W. J. Schoene (May 26): Rosy aphids are very numerous all through the 
central portion of the State. As a general rule the injury is restricted to 
sections of orchards rather than to whole orchards. 



-114- 

South Carolina. W. C. Nettles (May 22): The rosy apple aphid is causing consider- 
able damage at Clemson College. . 

Kentucky. W. A. Price (May 24): Rosy apple aphids have been abundant in many 
orchards of the State. Reports indicating injury have been received from 
Williamsburg, Pineville, Louisville, and Owensboro. 

Missouri. L. Haseman (May 23): Some rosy aphids are showing up in the central 
and northwestern part of State, though not serious. 

CODLING MOTH (Carp_ocap_sa pomonella L.) ... 

New York. N. Y. State Coll. of Agr. News Letter (May 15): In Ulster County on 
May 9 codling moth was found under bark in the pupal stage. 

P. J. Parrott (May 22): The codling moth is moderately abundant to very abunda 
in western New York. Fifty per cent of the larvae have pupated. 
P. J. Chapman (May 23): First codling moth captured in the field May 22. 

Pennsylvania. H. N. Worthley (May 24): The codling moth is moderately abundant at 
State College. The first emergence of adults occurred on May 15 at Biglerville 
Adams County, and on May 19 at State College, in Centre County. Warm weather 
the past few days has produced the first peak flight. Approximately 20 per 
cent of the spring brood had emerged on May 24 at State College. 

Delaware. L. A. Stearns (May 25): Ninety eight per cent of the overwintering 
larvae had pupated May 25; first emergence of spring-brood moths April 29; 
heavy emergence about May 20; first eggs May 16; first larvae May 24. 

South Carolina. 0. L. Cartwright (May 22): First eggs at Clemson College May 3. 

Georgia. C. H. Alden (May 19): The codling moth is scarce at Cornelia. Light 
first-brood injury. First-brood moths will be emerging around June 1. 

Ohio. T. H. Parks (May 22): Emergence of spring-brood moths commenced May 12 in 
Lawrence County, southern Ohio, and has progressed rapidly since. 

Indiana. J. J. Davis (May 26): First codling moths were reported at Vincennes 
May 3, but unfavorable weather following stopped emergence for some days. At 
Bedford, the first moths appeared at bait traps May 11, and the first eggs were 
laid May T5T ^e"Tan"^suaTly figure on 14 days between egg laying and hatching, 1 
but with the unusually favorable conditions the eggs began hatching at Bedford; 
May 23. The moths are coming out with a rush in southern Indiana, and it is 
likely that we will have one very large peak instead of two peaks for the first 
brood. There is a great abundance of codling moths throughout southern Indiana 

Illinois. W. P. Flint (May 20): The winter survival was not quite as great as 
has been the case during the past two years. From 50 to 75 per cent of the 
larvae survived in most cases. More emergence has been going on in southern 
Illinois for the past two weeks, and it is estimated that the first hatch will 
occur in the southern end of the State on the 17th or 18th. By the end of the 
month 'the first brood will be hatching up to the north-central part of the 
State. Nearly all overwintering larvae have pupated and we expect from present 
indications that the first brood will be rather bunched. 



-115- 

Missouri. L. Haseman (May 23): Emergence began in southern Missouri May 1, in 
central Missouri May 8, at Columbia May 17,. and in northern counties May 19. 

Hew Mexico. J. R. Eyer (April 21): Codling moths are very abundant. 

Wyoming. C. L. Corkins (May 10): Control measures are applied only occasionally 
in Wyoming. This appears to be one of the years when control is justifiable. 
A good crop last year, followed by an- exceedingly hot, dry summer, with a 
rising, infestation of the moths, laid the foundation for trouble this year. 

Idaho. R. W. Haegele (May 22): Beginning of spring emergence of moths occurred 
three weeks later than normal in southwestern Idaho. 

Washington. E. J. Newcomer (May 23): This is the latest season since 1922, as a 
result of almost continuous cool, cloudy weather since April 29. Practically 
no moths have been caught in baits in Yakima Valley. 

Oregon. D. C. Mote (May 9): B. G. Thompson reports development slow; only a few 
have pupated. 

EASTERN TENT CATERPILLAR ( Mai aco soma americana Pab.) 

Maine. C. R. Phipps (May 25): The eastern tent caterpillar is very abundant 

throughout the State. Nearly every unsprayed apple and cherry tree in western 
Maine is infested. 

H. B. Peirson (May 15): ■ The eastern tent caterpillar is very abundant in 
general over the State. Hatching started April 25 in Augusta. 

New Hampshire. L. C. Clover (May 24): The eastern tent caterpillar is very abun- 
dant, fully as much so as last year. Mr. Conklin reported them last year, and 
thinks they will be about the same this year, possibly a little more abundant. 
Bacterial wilt disease is evident in some of the webs. 

Vermont. H. L. Bailey (May 27): Eastern tent caterpillars are very abundant; 
more plentiful in' general about the State than they' have been since 1915. 

Massachusetts. A. I. Bourne (May 25) : The tent caterpillar seems to be present 
in greater abundance than for the last few years. This is particularly true 
of the eastern part of the State. Throughout practically all of that section 
the pest is present in great abundance along roadsides, particularly on the 
wild cherry, and on uncared-for fruit trees. A slight amount of evidence of 
its presence is found in some of the commercial orchards, although the regular 
system of spraying gives it little chance to make any headway. 

Connecticut. W. E. Britton (May 24): Considerably more abundant throughout the 
State than it was last year. 

Hew York. R. D. Glasgow (May 23): The eastern -tent caterpillar is unusually 

abundant throughout eastern New York. I have personally observed this insect 
in notable abundance from Long Island north to Elizabethtown, and I have seen 
unsprayed apisle trees 15 to 20 years old completely defoliated. 
N. Y. State Coll. of Agr. News Letter (May): In general the tent caterpillars 
are much more abundant than they were last year throughout the State. Their 



-116- 

nests are very conspicuous in wild cherry and other roadside trees and in 
neglected orchards. Entire defoliation was observed in many places "by the 
• middle of the month. (Abstract, J.A.H.) 

Pennsylvania. T. L. Guyton (May 22): The eastern tent caterpillar is very abun- 
dant generally over the State. 

Delaware. L. A. Stearns (May 25): The eastern tent caterpillar is very abundant 
in the northern part of the State. The first brood is about mature. 

Maryland. E. N. Cory (May 23): Heavy infestations in Prince Georges, Montgomery, 
Anne Arundel, Howard', Baltimore, Harford, Cecil," Dorchester, Wicomico, Caroline,, 
Charles, Garrett, Frederick, Alleghany, and Calvert Counties, hut not so heavy 
in Talbot, Kent, Carroll, Queen Anne s, Worcester, Somerset, and Washington 
Counties. St. Marys County not yet heard from. 

Tennessee. G. M. Bentley (May): Eastern tent caterpillars are very abundant. 
Adults are emerging. 

FRUIT TREE LEAF ROLLER ( Cacoecia argyrospila Walk.) 

Connecticut. P. Ga-rman (May 24): This insect is present in considerable numbers 
in two of the largest orchards of New Haven County. It appears in general to be 
on the increase. 

New York. N. Y. State Coll. of Agr. News Letter (May): During a warm spell which 
occurred the first week in May leaf roller hatching reached its peak in eastern 
New York and the hatch was starting that week in the western half of the State. 
In general this insect is more prevalent than it was last year throughout the 
State. (Abstract, J.A.H.) 

California. E. 0. Essig (May 22): Fruit tree leaf rollers are very abundant in 
the San Francisco Bay region on apricots and prunes. 

EYE-SPOTTED BUDMOTH ( Spilonota ocellana Schiff .) 

New York. N. Y. State Coll. of Agr. News Letter (May): During the first week in 
the month damage was noticeable in the Hudson River Valley.' Bud development 
was very rapid in the western part of the State, and very little injury 
occurred in that region. By the end of the' month some damage was ooserved 
in eastern New York. (Abstract, J.A.H.) 

Pennsylvania. H. N. Worthley (May 19): Overwintered larvae are now one-half to 
three-fourths grown at State College. 

BUFFALO TREEHOPPER ( Ceresa bubalus Fab . ) 

New York. N. Y. State Coll. of Agr. News Letter (May 22): A buffalo treehopper 
nymph was noted on May 19 in Clinton County. They were first noted' in Essex 
County on May 18. 

Pennsylvania. H. -N. Worthley (May 19): Oviposition scars are abundant on young 
trees, where there is an alfalfa : cover crop at State College. Eggs are nearly 
ready to hatch. 



-117- 

Nebraska. M. H. Swenk (April 20 to May 20): The buffalo treehopper v/as reported 
injuring apple and peach trees in Clay County the last week in April. 

LEAFHOPPERS (Cicadellidae) 

Massachusetts. A. I. Bourne (May 25): In general the infestation of leafhoppers 
seems to he rather light as yet. 

Connecticut. P. Garman (May 24): Apple leafhoppers ( Typhlocyba pomaria McAtee) 
are generally late in emerging from eggs on hark in New Haven County. It 
is still irrroossible to tell how abundant they will be. 

New York. N. Y. State Coll. of Agr. News Letter (May): During the latter part of 
the month T. pomaria developed in rather large numbers, and some stippling of 
leaves was observed in the eastern part of the State. Black leafhopper nymphs 
( Idiocerus provnncheri Van D.) were first found on May 4 in Ulster County. 
(Abstrrct, J. A.M.) 

P. J. Parrott (May 22): The apple leafhopper, T. pomaria , is moderately 
abundant in western New York. 

APPLE REDBUG ( Lygidea mendax Reut . ) 

:'New York. N. Y. State Coll. of Agr. News Letter (May): Redbugs began hatching 

in the lower Hudson River Valley the first week in May. By the middle of the 
month they were quite plentiful in this region and by the third week in the 
month were appearing in serious numbers in the western part of the State. 
(Abstract, J.A.H.) 

SAN JOSE SCALE ( Aspidiotus perniciosus Corns t.) 

Pennsylvania. T. L. Guy ton (April 28): The San Jose scale is scarce in Franklin 
County, and very abundant in central Pennsylvania. 

South Carolina. W. C. Nettles (May 22): The San Jose scale is very abundant at 
Clemson College. It is severe on apples even in sprayed orchards. 

Mississippi. C. Lyle and assistants (May): San Jose scale is generally prevalent 
throughout the State and was reported as very abundant during May in Monroe 
County and the northern half of the State. It was reported on apple at 
Biloxi, Harrison County, April 18; on hawthorn at Corinth, April 28. 
(Abstract, J.A.H.) 

Oregon. 3. G. Thompson (May 9): San Jose scale infestation is apparently more 
serious than last year at Cottage Farm, Salem.

Ne.w Hampshire. L. C. Glover (May 24) : : European red mite hatched the week of May 8, 

Massachusetts. A. I. Bourne (May 25): The overwintering eggs were observed to "be 
hatching on May 1, and "between that date and May 4 they had hatched very 
generally throughout the State. 

New York. N. Y. State Coll. of Agr. Hews Letter (May): During the last few days 
in April red mites began hatching in the Hudson River Valley. By the first 
week in May they. were out in numbers and apparently more abundant than last 
year. By the end of the month considerable bronzing was observed in the 
Hudson River counties. (Abstract, J.A.H.) 

PEACH 

ORIENTAL FRUIT MOTH ( Grapholitha molesta Busck) 

Connecticut. P. Garman (May): Damage is not yet apparent, but we are expecting 
a large number in orchards because of the mild winter. Moths are just emerging 

New York. P. J. Parrott (May 22): The oriental fruit moth is moderately to very 
abundant in western New York; emerging in large numbers. 

Delaware. L. A. Stearns (May 25): Overwintered larvae 100 per cent pupated May I 
peak of spring brood emergence April 30 to May 4; first eggs April 28; first 
larvae May 5. Twig injury conspicuous May 22~24. 

South Carolina. W. C. Nettles (May 22): The oriental fruit moth is severe in peac] 
orchards in Clemson College and Greer. 

Georgia. 0. I. Snapp (May 19): Considerable twig injury in one orchard at 
Culloden. ;

to peach trees was also reported from New Albany, Union County, on April 20. 

PLUM CURCULIO ( Conotrachelus nenuphar Hbst.) 



Massachusetts. A. I. Bourne (May 25): The plum curculio is emerging from 

hibernation and coming into the orchards in rather large numbers. We have just 
begun to note, within the last two or three days, the first evidence of feeding 
and egg-laying scars on cherries and plums. 

New York. N. Y. State Coll. of Agr. News Letter (May): The first plum curculio 
to be jarred from a tree in the eastern part of the State was collected May 11 
This is the same date that the first beetle was collected last year. During 
the last week in May feeding punctures were found on cherries and pears. 
(Abstract, J.A.H.) 



-119- 

Delaware. L. A. Stearns (May 25) : First emergence of plum curculio from hiber- 
nation April 18; peak May" 9; first-brood grubs three-fourths nature and drop 
of infested peaches, began May 24, 

Maryland. £. N. Cory (May 22): The plum curculio is moderately abundant. It is 
late in emerging in numbers at Hancock.

noted in the Nashville district. Larvae v/ere entering soil in small numbers 
May 11. 

Georgia. 0. I. Snapp (May 18): Full-grown larvae began to leave peach drops on 
April 29, and the peak of first-brood larvae emergence occurred on May 7. at'" *.. 
Fort Volley. The .£ir*st_ pupation of the season was recorded on May 18. Pupation 
is earlier .than in 1932, and a second brood of this insect is expected here 
this year. The general infesto.tion is heavier than last year, but lighter 
than that of an average year. (May 21): Emergence of Triaspis curculionis 
Fitch, a common hymenopterous parasite of curculio larvae, started today. 
Parasitise:, is expected to be heavier than usual on account of the high per- 
centage of small curculio larvae this year. 

G. F. Moznette and H. S. Adair (April 26): The plum curculio is reported by 
local peach growers as being much less abundant in this locality (Albany) than 
in former years. The infestation was so light that the first spray was omitted. 
The small number early in the season is probably due largely to the total 
absence of a peach crop during 1932 in this locality. 

C. H. Alden (May 19): The plum curculio is moderately abundant at Cornelia. 
There is 20 per cent infestation in sprayed drops, 73 per cent infestation in 
unsprayed drops. 

Illinois. J. H. Bigger (May): May 18 at Grafton I saw feeding which appeared 
to be 2 to 3 days old. Oviposition cuts were also present.

central Missouri. It began work May 16. 

iArkansas. P. P. Sanders (May 24): Pupae were found in cages today. a^ Nashville. 
Two broods are almost sure to occur since the commercial crop of peaches does 
not move until July 15 - 20. 

Mississippi. C. Lyle and assistants (May): . The plum curculio is reported as very 
abundant throughout the greater part of the State. 

CAMBIUM CURCULIO ( Cono tracheitis an aglypticus Say)

with the statement that the "beetles were seriously injuring "buds and foliage 
on peach trees in Scioto County. 

RUSTY PLUM APHID ( Hysteroneura setariae Thos.) 

Tennessee. H. G. Butler (May l): An infestation of the rusty-brown plum aphid was 
found on peach April 28. This infestation was found on the property of one of 
the better orchardists and is reported by him to be the first he has seen. I 
have not previously found this insect at Harriman in the past 3 years. This 
is thought to be the first record of this insect as a peach pest in this 
district. These insects are to be found on only a few trees. 

PEAR. 



PEAR MIDGE ( Contarinia pyrivora Riley) 

New York. N. Y. State Coll. of Agr. News Letter (May): The pear midge ?/as flying

farm near Barnesville and badly injured the blossoms in a short time. 

BLACK CHERRY APHID ( Myzus cerasi Fab . ) 

Hew York. N. Y. State Coll. of Agr. News Letter (May): The black cherry aphid was 
very abundant throughout the State. In most of the commercial sections control 
measures were necessary. (Abstract, J.A.H.) 

PLUM 

PEAR THRIPS ( Taenio thrips inconsequens Uzel)

PECAN 

PECAN NUT CASS BEARER ( Ac rob as is caryae Grote) 

Georgia and Florida. C. F. Moznette and H. S. Adair (April 24): The characteristic] 
spring shoot injury caused by this insect has been very difficult to find on 
pecan trees this season at Monticello, Fla. , and Baconton, Leesburg, Cairo, andi 
Albany, Ga, This condition indicates that this insect may not be abundant 
enough during the first generation to cause serious damage to the nut crop. 

Texas. F. L. Thomas (April 24): Pecan nut case bearers are very scarce this year 
in the Brazos River bottoms of Brazos and Ft. Bend Counties.

did not spray for this insect last season considerable damage is being done. 
In the vicinities of Monticello, Fla., and Cairo and Albany, Ga. , where this 
insect is abundant, damage is not only noticeable on the buds and foliage, but 
the spring shoots are being damaged, and in many instances complete severing 
of the shoots at the base is observed. 

HICKORY SEUBK-. WORM ( Laspeyresia caryana Fitch) 

Georgia. H. S. Adair (April 24): Fourth-instar larvae were observed feeding in 
phylloxera galls on the leaf stems of hickory at Albany. Although moths have 
been observed in pecan orchards throughout the month, no larval feeding has 
been recorded and only a single egg was found on pecan leaves April 21. 

SMALLER WEB WORM ( Tetralopha sub canal is Walk.) 

Georgia. J. B. Gill (May 25): The caterpillar T. subcanalis is occurring more 
commonly on pecan trees of Albany than in former years.

present on pecan foliage on this date at Albany. 

OBSCURE SCALE ( Chrysomphalus obscurus Corast.) 

Mississippi. C. Lyle and assistants (May): One of the heaviest infestations that 
I have over seen was noticed on a pecan tree at Vicksburg on May 9. The scale 
""Was injuring the tree seriously. 

PS CAN PHYLLOXZRA ( Phylloxera devastatrix Perg.) 

Mississippi. C. Lyle and assistants (May): A heavy infestation was noticed on a

South Carolina. E. Sherman (May 22): The bean leaf beetle is more abundant than 
it has been for the last 4 or 5 years. 

W. J. Reid, jr. (April 20): The bean leaf beetle is quite abundant on snap 
bean plantings in the commercial growing areas around Charleston. The infes- 
tation is suffciently great to warrant control measures, especially since 
the plants are being retarded by dry soil conditions. ■; 

Georgia. W. H. Clarke (May 8): A small area of field peas at Thomaston had 

been injured to such an extent that replanting has been necessary. Consider- 
able numbers of the beetles are present on beans in gardens.

CABBAGE APHID ( Brevicoryne brassicae L.) 

South Carolina. W. J. Reid, jr. (April 25): •' Until parasites became sufficiently 
numerous apparently to have the infestation under control, the cabbage aphid 
threatened to do serious damage to late spring plantings of cabbage in the 
Charleston area. About 5 per cent of the young plants were rendered useless 
by the aphids before the parasites appeared in large numbers^ 



-129- 

Tennessee. J. Milam (May 24): The cabbage aphid is probably more abundant at 
Clarksville than for some years. Considerable damage is being done to

South Carolina. W. J. Reid, jr. (May 24): The onion thrips infestation of 

cabbage, previously reported as appearing in the Charleston area, about the 

middle of April, gradually increased throughout May. As a result of dry, 
hot weather and thrips injury the growth of cabbage plants is now practi- 
cally at a standstill. This is particularly true in the case of immature 
plants. Unusually dry and hot weather conditions have existed during May and 
there has been a serious lack of rain since early March. 

CUCUMBER 

PICKLE WORM (Diajohania ni tidal is Stoll)

fairly numerous in a lav_,e field of potatoes. 

North Carolina. Z. "P. Metcalf (May 5): Tobacco flea beetles are very abundant. 
Owing to the excessively hot, dry weather which has greatly retarded recently 
planted tobacco, the flea beetle has done more damage in this State than at 
any time in the last 25 years. It is reported generally from the .eastern 
part of the State. 

Tennessee. G. M. Bentley (May): The tobacco flea beetle is moderately abundant

inspectors of the brown-tail moth distribution beyond the quarantine line 
show a definite spread in Maine northeast of the present quarantine line, 
and in New Hampshire north and west of the present quarantined area, in- 
cluding several towns in Vermont. This survey work has not yet been com- 
pleted. Reports have been received that the infestation in the southwest- 
ern part of Maine, including York .and Cumberland Counties, and the southern 
parts of Oxford and Androscoggin Counties, are more heavily infested than 
usual. There have also been reports of heavy infestation as far east as

owner noticed them. When the tree was visited the larvae were wandering 
about over tree and ground and crawling up a nearby building and fence. 
Thousands of the larvae had attempted to go up the tree trunk again after 
dropping to the ground. This is the first Ohio record of injury from 
this sawfly that has come to us. 

CARPS HTER WORM ( Prionoxystus robiniae Peck) 

North Dakota. J. A. ?!unro (May 20): The carpenter worm is doing much damage

troublesome in some parts of Westchester County and of Long Island. 

Maryland. E. N. Cory (May 19): The first record of emergence was obtained 

Wednesday on cage specimens at College Park. The webworm has been reported 
from Baltimore City. 

JUNIPER SCALE ( Diaspis carueli Targ. ) 

New York. P. J. Parrott (May 22): The juniper scale is moderately abundant in 
. western New York. 



-136- 
A SOFT SCALE ( Lecanium flctchcr i Ckll.) 

Kansas. H. B. Hungcrford (May 11): Me found quite a heavy infestation on red

dant at Florence on maple leaves. 

Mississippi. C. Lyle (May 23): A heavy infestation was observed on maple trees 
in Starkville on May 15. Migratory forms were already present, however. 

PINS 
EUROPEAN PIKE SHOOT MOTH ( Rhyacionia buo liana Schif f . ) 

New York. R. D. Glasgow (May 23): This insect is now causing extensive and very 
serious damage to red pines in ornamental plantings and on small afforested 
areas; it has been distributed with infested nursery stock until it is now es- 
tablished in ornamental plantings in or near most of the larger cities of the 
State, -and apparently promises to become a pest of major economic importance. 

PALES WEEVIL ( Hylobius pales Boh. ) 

New York. R. D. Glasgow (May 23): The pales weevil is causing severe injury to 
several pine species, but particularly to Scotch pine in the neighborhood of 
Saratoga Springs and Glens Falls. This insect is destroying many trees, not 
only in young Scotch pine plantations but also in plantations 15 years old or 
more. I have recently found this insect to be responsible for considerable 
losses in a '.Testchester County nursery, where it has caused very serious dam- 
age both to Scotch pine and to Mugho pine. 

A iTEEVTL ( Hypomolyx -piceus DeG. ) 

New York. R. D. Glasgow (May 23): This weevil has recently been found responsi- 
ble, in the higher altitudes of northern New York, for severe injury to Scotch 
pine plantations similar to that which has been caused by the pales weevil in 
the neighborhood of Saratoga Springs.

AMARYLLI S 

A MITE ( Tarsonemus approximatu s narcissi Ewing) 

Washington. C. F. Doucette (May 11): From April, 1933, report, Sumner, Wash., 
Station: Mites of what is considered this species (T. approximatus narcissi ) 
and variety were found on bulbs of Hippeastrum sp. (hybrid amaryllis) in the 
laboratory greenhouse. The extent and numbers of the infestation indicate . 
that this mite is distinctly able to exist on this plant. An authoritative 
determination has not been received as yet, as males seem to be still quite 
scarce. This is the first knowledge of the occurrence of this mite on any 
plant other than narcissus. 

AR30RVITAE 

ARBORVITAE APHID ( Lachnus thu.jafalinus Del G.) 

South Carolina. W. C. Nettles (May 22): This aphid is abundant on arborvitae 
at Clemson College.

injurious numbers. Yard plantings of cannas at Biloxi have been attacked to 
such an extent that they appear very unsightly. 



-137- 

CREFE MYRTLE 

CREPE MYRTLE APHID ( Myzocallis kahawaluokalani Kirk.) 

Mississippi. C. Lyle (May 23): Crepe myrtle twigs showing a medium infestation 
were received from Kosiusko, Attala County, on April 20. Aphids were found

buds of larkspur at New London, Yalesville, and New Haven. 

NARCISSUS 

NARCISSUS BULB FLY ( Mere don eouestris Fab.) 

Washington. C. H. Martin . From April, report, Sumner, Wash., Station: During 

March the majority of the larvae of M. eques t ris had left the bulbs to pupate. 
On March 28 larvae remained in 8.3 per cent of the infested bulbs. These 
figures include larvae of all sizes, including the supposed two-year forms. 
On April 24 there still were some full-grown larvae within the bulbs which 
had not pupated. April 12. Adults of both types of bulb flies were observed 
flying near the laboratory cages. Surveys in commercial fields did not show 
any adults. The large number of pupae being carried this season under various 
conditions gives the -orobable explanation of this very early emergence, and it 
is not considered as a definite date for the emergence of flies under normal 
conditions. April 27-28. Adult Merodon were again seen around the laboratory 



-138- 

cages, "but were not observed in Puyallup Valley fields. No emergence had "been 
observed in pupae (several hundred) caged for emergence data. Reports from 
growers in the Portland, Oregon, area stated that several adults were 
observed there in fields April 25-30. 

TAXUS 

BLACK VIUE WEEVIL (B rachyrhinus sulcatus Fab.) 

New York. S. D. Glasgow (May 23): The black vine weevil has been very injurious 
to taxus in many parts of eastern New York and Long Island. About two weeks 
ago at Garden City, L. I., I personally collected 34 larvae (not yet reared 
through for identification, but presumably of this species) from about the 
roots of single small taxus plant not over 18 inches high. 

VIRGINIA CREEPER 

LEAFHOPPERS ( C ic a de 11 i dae ) 

Utah. G. F. Knowlton (May 23): From recent identifications it appears that 

Erythron ura ziczac Walsh is the most common leaf hopper damaging Virginia creepe 
in northern Utah, with E. elegans McA. being next in abundance upon this 
ornamental climber. 

South Dakota. H. C. Severin (May 20): Woodbine leafhoppers are unusually abundant 
for this time of year and are already doing considerable damage to woodbine 
and related plants. 

INSECTS ATTACKING MAN AND 

DOMESTIC AN- 1 M A L S 

MAN 

TROPICAL RAT MITE ( Liponyssus bacoti Hirst)

HORSE 

HORSE FLIES (Tabanidae) 

Georgia. W. I. Eove and E. G. Hall (May 27): Tabanus costalis Wied. "began to 
appear in the vicinity of salt marshes about May 10, and on May 27 they were 
about as acuncant as they were last year. They are severe biters of man and 
have a seasonal incidence which follows that of Culicoides cani thorax Hoffm. 

Texas. E. C. Cashing (May): After a general heavy rain on Hay 14, Tabanidae began 
to cause some annoyance to livestock by May 18. By May 23 they became quite 
troifclesome, especially in the bottoms along rivers and creeks. 

BOTFLIES ( C-astrophilus spp.) 

Iowa. Z. F. Knipling (May 26): First larva of G. haemo r rho i dal i s L. was found 
attached in rectum of horse May 1. First dropping larva of G. nasal is L. was 
t alien "on May 13. Fecal examination of horses since that date indicates that 
this species is dropping in considerable numbers. First dronping larva of 
G. intestinal is EeG. was taken May 19. Previous examinations of feces were 
negative. 



-140-

abundance of ants, both in lawns and dwelling houses. The number of complaints 
of both types of activity has been unusually large for this part of the season. 

Mississippi, C. Lyle (May 23): On May 16 a correspondent at Quitman, Clark County 
sent us specimens of the Eiorida harvester ant, Pogonomyrmex badius Latr. with 
the following statement: "These ants build their nests in my farm and won't 
let anything grow near them." Reports have been received from various sections 
of the State regarding the abundance of fire ants, Solenopsis geminata xyloni 
McC. in lawns and flower beds. Prenolepis imperis Say var. testacea Emery 
were causing considerable annoyance in a kitchen at Tupelo on May 1. 



-141- 

WHI IE -MARKED SPIDER BEETLE (Ptinus fur L.) 

Ohio. T. H. Parks (May 3): A home near Columbus was found to "be infested with 
these beetles. They were brought into the h/me in an old quilt brought from 
Illinois. This quilt was found to be well populated with the insect. The 
beetles were scattered all through the interior of the quilt where they had 
caused no serious damage except their presence. To all appearances they had 
hatched inside and fed on the cotton filling. This is the first time this pest 
had been called to our attention as a household insect. 

Minnesota. H. E. Shepard (May): The white-marked spider beetle was found in 
large numbers on stored flour at Duluth, St. Louis County, May 4.

THE MORE IMPORTANT RECORDS' FOR JUNE, 1933 

The grasshopper" situation in. the Dakotas, Minnesota, and eastern Montana 
is as serious as was anticipated from the surveys carried on last year. Ex- 
tensive campaigns are being carried on throughout the infested districts. 
Scattered outbreaks were also reported from Iowa and Nebraska, ■ and southward 
through Kansas and Oklahoma to Mississippi and Texas. Outbreaks are also re- 
ported from localities in Wyoming, Utah, and Nevada. In the upper Mississippi 
Delta airplanes were used in attempting to control the outbreak of hoppers. 

The black cutworm, or so-called overflow worm, developed in outbreak 
numbers in the lowlands of southwestern Indiana, Illinois, and Ohio. The clay- 
backed cutworm occasioned serious injury in central and northern Illinois, the 
pale western cutworm was troublesome in northeastern Colorado and north-central 
North Dakota, and the variegated cutworm has been reported from Virginia, 
Tennessee, and Missouri. 

Toward the end of June considerable outbreaks of armyworms were reported 
from Pennsylvania, Virginia, West Virginia, Indiana, and Tennessee. 

The garden webworm was reported as destroying alfalfa in parts of Indiana, 
and a general and rather severe infestation of webworms on both sugar beets and 
alfalfa was reported from Minnesota, Montana, Wyoming, and Utah. 

An unusual and severe infestation of crotalaria by the bella moth was re- 
ported from Georgia through Alabama to Louisiana. 

Rose chafers have been unusually and distinctively abundant in the New 
England States and westward through New York to Indiana and Michigan. 

Despite the setback the chinch bug received during May by heavy rains, 
this insect was reported as still appearing in serious numbers in Ohio, through 
Indiana to central Illinois, and in parts of Iowa, Missouri, and Nebraska, 
southward through Kansas to Oklahoma and Texas. 

The lesser corn stalk borer was reported during the month as damaging 
both sugarcane and corn in the Gulf States from Louisiana to Georgia and 
Florida. 

The codling moth is very abundant throughput, the Eastern States. The 
infestation in Illinois is reported as the most serious in the past 20 years. 

The rosy apple aphid built up destructive populations during early June 
in the Middle Atlantic States. 



-145- 



-146- 

Blister beetles, which in the grub stage are predacious on grasshopper 
eggs, were reported as ■"■unusually: destructive to truck crops in the South 
Atlantic States, from Virginia westward to Kentucky. In the region heavily 
infested by grasshoppers last year these insects, became decided pests to both 
field and garden crops, reports having, been received from the two Dakotas, 
Nebraska, Kansas, and Wyoming. 

The false chinch bug was very abundant during the -middle of the month in 
the West Central States, reports having been received from Iowa, Nebraska, and 
Kansas. It was also reported from Colorado, Utah, and California. In California 
the outbreak is the worst ever recorded. 

The Mexican bean beetle continues to be seriously abundant throughout its 
entire range. 

Brood XIX of the periodical cicada, the largest of the 13-year broods, 
appeared during late May and early June over the greater part of the territory 
known to be infested. This brood covers the territory from central Illinois 
and northeastern Missouri southward over Arkansas and eastern Oklahoma to the 
northern border of Louisiana and extends eastward across Tennessee and Alabama 
into Georgia and the Carol inas. 

Fall and spring canker worms were generally prevalent from, the New England 
States and New York westward to the Dakotas and Nebraska. 

The forest tent caterpillar is abundant throughout the mountainous regions 
from Maine southward to central Virginia. An outbreak of this insect is also 
reported from northeastern Colorado. 

THE MOST IMPORTANT ENTOMOLOGICAL FEATURES IN CANADA FOR JUNE, 1933. 

Over a large part of the Dominion the spring season was cool and' late, 
and work on the land and seeding operations were reported more backward than 
in any year since 1928. A report at the end of May stated that throughout the 
West general soil-moisture conditions were better than for several years. 
However, in June there were complaints of shortage of moisture in certain 
areas of the Prairie Provinces and more precipitation would be welcomed, 
particularly in west-central Saskatchewan and in southwestern and central 
Alberta. 

In general, reports from various parts of eastern Canada and British 
Columbia indicate that insect damage to field and fruit crops, so far, is 
comparatively light. In the prairie Provinces the hatching of grasshoppers 
was general by the first week in June over considerable areas and, as expected, 
an outbreak of serious proportions was developing. Strenuous efforts to cope 
with this outbreak by means of poisoned baits are being made. 

Cutworms appeared to be less threatening in the Prairie Provinces than 
during the past few years. Local losses due to the pale western cutworm 
occurred in Alberta and at various points in central and east-central 
Saskatchewan, but in both Provinces the outbreak of this species was generally 
less severe than in 1932. Exceptionally few complaints of cutworm damage have 
been made in the Okanagan Valley, British Columbia, but considerable trouble 



-14 7-. 

from these insects was reported.- from the Kami oops district. Some truck and 
garden crops in southern Quebec were seriously attacked "by cutworms, and local 
damage by several species occurred In some secti-ons of- Ontario. 

. Extensive damage to grain by wireworms was : reported in Alberta -and in the 
. As si nib oia- Swift Current area ,of Saskatchewan., Local damage by wireworms was 
noted in eastern Ontario. 

Injury by white grubs is already heavy in eastern Ontario where beetle 
flight? occurred in 1932. The damage will reach its maximum this year in the 
autumn. White-grub infestations were reported from southern Quebec and south- 
ern Few Brunswick. 

Flea beetles have again proved troublesome on truck crops in parts of 
British Columbia, and on garden truck and sugar beets locally in southern 
Alberta and Saskatchewan. Local damage by flea beetles was also noted from 
Ontario and southern Quebec. 

The cabbage maggot has caused some damage in the Okanagan valley, British 
Columbia, and root maggots are generally abundant on irrigated truck farms in 
the Lethbridge area, Alberta. 

Insect pests of the apDle are generally less in evidence than usual in the 
Annapolis valley, Nova Scotia. 

An unusually severe outbreak of grape leafhoppers is expected in the 
Niagara district, Ontario, unless control measures are adopted. In this section, 
too, there is an outbreak of the black. cherry aphid which is proving unusually 
troublesome on sweet cherry. 

Observations at certain points in the Niagara district, Ontario, indicate 
that the population of overwintering adults of the oriental fruit moth was small 
compared with 1932. The spring brood was considerably smaller than that of 
last year and twig injury was reduced. It is too early to estimate accurately 
the final size of the generation. 

Outbreaks of leaf-eating caterpillars in certain parts of Ontario:, and in 
the eastern townships of Quebec, were given much newspaper publicity in early 
June. Tent caterpillars and canker worms apparently were the chief species 
concerned. A heavy infestation of cankerworms also extended along the Red River 
valley, Manitoba. A decided increase of tent caterpillars was evident through- 
out eastern Canada this season. 

A general infestation of the willow leaf beetle developed in Saskatchewan 
and Manitoba, on poplars and willows, and a heavy larval infestation is likely 
to follow. Larch foliage was again severely attacked in Eastern Canada by the 
larch case bearer. 

In many parts of the Dominion mosquitoes and blackflies are proving more 
numerous and troublesome than during recent years. Severe infestations of 
mosquitoes have been reported in Quebec, Ontario, Manitoba, and British Columbia; 
an unusual abundance of blackflies have been noted in parts of Ontario, partic- 
ularly in forested sections. 

Recent reports indicate that among stored-product pests, spider beetles, 
Ptinus spp., are i^revalent in many parts of the Dominion.

GRASSHOPPERS ( Ac r i di dae ) 

Illinois. .W..P. Flint (June 19): Grasshoppers have "been hatching for the past 

two weeks in central Illinois. ' They are slightly more abundant than last year. 

Wisconsin. C. L. Fluke (June 19): Grasshoppers are very abundant . 

Minnesota. A. G. Ruggles (June 26): Fifty-five co-unties are organized for control, 
Control has "been perfect. 

North Dakota. J. A. Munro (June 15): Grasshoppers are generally prevalent over 

the areas indicated oy the 1932 Federal survey. The situation is very serious | 
in the southwestern counties and a,. few of the north-central counties. 
F. D. Butcher (June 12): Hatching In the eastern and northern parts of the 
State seems to "be almost over. I find a few fourth-instar Melanoplus bivittafus 



Say now, "but most of them are younger. Rains of the la.st .ten days, which have 
"been intermittent, are responsible for destroying a. few of those wiiich had been 
out only a. few hours. (June 20): There has "been no material change in the 
situation in the State during the past week. All the eggs except possibly 
those of M. differentialis Thos. have hatched. The hatching period has been 
of shorter duration than it was a yea.r ago. Very high temperatures the last 
few days of last week brought many hoppers from the roadside's into the fields. 
(June 21): I saw my first adult M. bivittatus today. R. L. Shotwell reports th 
on June 19 he saw one adult and one f irst-instar nymph near Dickinson, Stark 
County. lie also reports seeingan adult M. mexicanus Sauss. on June 16. 

South Dakota. H. C. Severin (June): Grasshoppers are very abundant, chiefly M. 

differential is ,. M. bivittatus , and M. mexicanus , but not so abundant as in 1931 j 

Iowa. C. J. Drake (June 19): Grasshoppers have appeared in destructive numbers in 
Woodbury and Plymouth Counties, in areas not poisoned last year. M. 
differential i s and M. bivittatus are' the principal species involved. 

Nebraska. M. H. Swerik (May 20 - June. 20)': . Grasshoppers were hatching in southern 
Nebraska by May 13, but not in the large numbers in which they appeared in 1930, 
1931, and 1932. However, in northern Nebraska, grasshoppers have again hatched 
out in the same large numbers as during the past three springs. They became 
much in evidence in the pastures and small grain's about June 1, and a week or 
ten days later it became evident that very serious damage to the corn was 
impending. The chief species concerned were M. bivittatus , M. differentialis , 
and M. femur-rub rum DeG. , though there were also unusual numbers of adults of 
Parcielophora (= Hip p iscus ) haldemanii Scudd. and P. apiculata Say as well as 
nymphs of Arphia sp. On June 13 the M. bivittatus nymphs were mostly in the 
third instar, while those of M. differentialis were mostly" in the second instar. 
Some M. femur- rub rum were adult. Several carloads of poisoned-bran bait were 
shipped into this section about the middle of June. 



Kansas. H.. R. Dryson (June 22)': Grasshoppers are more plentiful at Manhattan this 
year than last. Reports have been received from Madison and Grenola. M. 
bivittatus is the most numerous.

Oklahoma. C. F. Stiles (June 13): Grasshoppers' of various species are very numerous 
in pasture land in Cusbar, Roger Mills, and Beckham Counties and parts of Kiowa 
County. If dry we'a^he p.: continues, we expect considerable damage to the cotton 
, fields located near pasture land. So far M. different lalis , which does the 
most damage in Oklahoma, .has not made its appearance in large numbers. 

Mississippi. C. Lyle (June 22): ' On June 15, grasshoppers, chiefly M. differential!'. 
ware causing great (Lunate to thousands of acres of corn, soybeans, and cotton 
at Parchman. In several field::, the cotton had been destroyed completely. The 
hoppers seemed to prefer' soybeans and had completely stripped hundreds of acres 
of this crop. Most of the hoppers were about half grown or younger. All the 
land had been broken during the winter, ditch banks closely plowed, and all 
field margins cleanly cu) tivated, but there were myriads of the hop2oers present 
. in spite of tiiece preventive measures. Because of the necessity for quick 
action, three airplanes were being used to dust with calcium arsenate while 
poisoned bait was being distributed in large quantities. Lack of rain for two 
or three months past increased the severity of the outbreak. 

Texas. F. L. Thomas (June 21): Gra.sshoppe.rs are very abundant at Calvert and 
Barstow, where they practically destroyed the cotton in a 10-acre field. 

Montana. A. L. Strand (June 20): The northeastern counties in Montana are suffer- 
ing from a severe outbreak of the lesser migratory grasshopper, M. mexicanus . 
This outbreak centers in Valley and western Daniels and Roosevelt Counties. 

Wyoming. C. L. Corkins (June 20): Grasshoppers are very abundant. The Bighorn 
Basin has the worst grasshopper outbreak in its history. Five cars of poison 
are now out and the job is about half completed. 

Utah. G. F. Knowlton (June 15): Grasshoppers are causing more or less damage in 
various localities throughout the State. But in general the populations are 
lower than at this time during the past two seasons. Early nymphs of a few 
species had become adults by June 9, in the Grantsville - Flux areas. Adults 
of M. mexicanus , M. bivittatus , Trimerotropis vinculata Scudd. , and two other 
species were taken. 

Nevada. G. G. Schweis (May): Grasshoppers of several species are reported as very 
numerous in various parts of western Nevada. It is anticipated that control 
mea.sures will be necessary. 

CUTWORMS (-Mb c-tui da e ) 

Tirginia. 1. J. Schoene (June 23): Cutworms have been reported as injuring field 
crops in several sections. Barley and rye were the main crops injured, 
although corn suffered to some extent. In some fields near Timberville the 
damage to barley reached 90 per cent. Reports of injury were also received 
from the bottomland on the James River east of Richmond. 

Ihio. T. H. Parks (June 14): The black cutworm has destroyed 50 acres of corn 
in Franklin County river bottom land which overflowed in March. It is not 
present in upland corn. Larvae are nearly full grown now. Received specimens 
also from Clinton and Fayette Counties with the statement that they had 
destroyed l/3 of the plants in a few fields. Also attacking corn at Columbus. 



-150- • 

Indiana. J. J. Davis (June SO): Frobahly the outstanding insect -.outbreak of . the 
: ..■•■month has "been that, of -the ••'black or greasy cutworm ( Agro;tis ypsilon Sot.t»)i 
. which is known as the-' overflew worm in the southwe stern part of the State.. We 
had a report of cutworms from Knox, June 5, the species involved being unknown. 
However, we have authentic specimens from Otterbein, Newtown, and Kokomo, the 
first report being received June 13, at which time all stages of cutworms were 
observed. .Reports from the vicinity of Fowler indicate that thousands of acres 
of corn have been taken* 

Illinois. W. P. Flint (June 19): Several species of cutworms have been causing 
serious injury in central and northern Illinois. In the low or overflow areas 
along the rivers the damage has been caused mainly by the black cutworm, A. 
ypsilon . In the north-central part of the State many spring-plowed fields 
have been seriously damaged by the clay-backed cutworm, Feltia gladiaria Morr. 
These tv/o species are by far the most destructive and abundant this year. 

Tennessee. G. M. Bentlej^ (June): A. yosilon and Lycophotia nargarito sa saucia Hbn. 
are very abundant in eastern and middle Tennessee. 

North Dakota. J. A. Munro (June 15): A report from Bantry (Mc Henry County), June 5 
states that cutworms ( Porosagrotis orthogonia Morr.) are widespread and have 
destroyed large fields of corn and other crops. 

Iowa., C. J. Drake (June 19): Cutworms, here and there, have done considerable 

damage this spring. The county agent reported that the cutworms have destroyed 
a 10-acre field of corn in Montgomery County. 

C. N. Ainslie (June 12): Various species of cutworm moths are unusually" 
abundant this spring in northwestern Iowa, and are a general nuisance because 
of their habit of entering houses and hiding during the day in dark corners or 
behind screen doors. They are reported attacking gardens in Woodbury County. 

Missouri. L. Hasenan (June 24): A very heavy infestation of variegated cutworms 
(L. nargaritosa saucia ) occurred in the eastern counties in alfalfa. Dipterous 
parasites are , very abundant. Pew moths have emerged. 

Nebraska. M. H. Swenk (May 20 - June 20): Cutworms have been reported as numerous 
in Garden County the last week in May and also in Dawes County the middle of 
June. A complaint concerning damage in alfalfa by the dark-sided cutworm 
( Duxoa me s so r la Harr.) was received on June 3 from Perkins County. Numerous 
inquiries were received concerning a great abundance of the moths of the army 
cutworm (C horizagrotis auxiliar is Grote) . These reports came from Pierce, 
Madison, Boone, Keith, and Lancaster Counties from June 7 to 13. 

Mississippi. C. Lyle (June 22): On May 23 G. I. Worthington sent us a' number of 
beetles collected from an alfalfa field at Shaw in Bolivar County, which had 
previously shown a heavy infestation of cutworms. He wrote that the ground was 
alive with these beetles, there being one every 6 inches over 40 acres. 
Specimens were identified by L. L. Buchanan as Anisodactylus sericeus Harr. 

Texas. P. L. Thomas (June 21): Cutworms are very abundant and damaging' alfalfa. 






-151- 

ARMYWOEM ( C irphis unipunc ta Haw . ) 

Pennsylvania.. C. A. Thomas (June "21) : A considerable outbreak of army wo rr.is is now 
occurring in southern' Chester County, -especially in the area "between West Grove 
and Oxford, along Route 1.' Six farms in this area were found to 'be more or less 
infested, one farm .showing an 80 per .cent reduction in barley because the worms 
cut' off "' the heads. An unidentified tachinid fly laid eggS upon approximately 
25 per cent of the larvae in one field, but the parasitization in other fields 
was very low. ., Starlings and grackles ate many. of the larvae. Corn and alfalfa 
were also severely injured in some fields. 

lest Virginia. L. M. Peairs (May 26): Armyworms are numerous but scattered; they 
are full grown. .... ,. 

Maryland. E. IT. Cory (June 22): Armyworms are doing serious injury to barley, 

wheat, and pastures in Kent, Somerset, St. Marys,. Baltimore, Harford, 'Frederick, 
and Washington Counties. 

Washington, D. C. W. R. Walton (June 22): A heavy flight of armyworm moths occurre* 
last night, and many moths are flying about in buildings today. 

Tennessee. C. Benton (May 2C) : Twenty acres of mixed barley and clover were 

seriously injured near Petersburg, Lincoln County '. Barley was practically all 
cut off about an inch below the heads. 'Crimson clover leaves are largely eaten 
but the heads are undisturbed. Worms will be about full grown by May 31. 

SOD WEB WORMS (Crambinae) 

Kentucky. W. A. Price (June 24): Sod webworms have been especially troublesome in 
corn and tobacco fields. Many fields have one third of the crop ruined by these 
pests. 

: Tennessee. C. Benton (May 31): Some damage by sod webworms to newly set tobacco 
plants near Fayctteville, Lincoln County, is reported. 

WEBWORMS ( Loxostege spp.) 

Indiana. J. J. Davis (June 20): The alfalfa webworm (L. similalis Guer..) was 
reported as destructive to alfalfa at Elkhart, May 31. There is indirect 
information that this pest may have been destructive elsewhere. 

Minnesota. A. G-. Ruggles (June 26): The sugar beet webworm is reported as bad in 
Freeborn County on onions and in Redwood County on corn. 

Montana. A. L. Strand (June 20): The beet webworm moths have been flying since the 
last few days in May. Many eggs and young larvae are now present. An outbreak, 
somewhat less intense than that of 1932, is expected. 

Wyoming. C. L. Corkins (June 20): Alfalfa webworms are now hatching. There will 
be spotted infestations of both the alfalfa and sugar beet webworms, but not 
the general infestation of last year and not nearly so much damage. 

Colorado. G. M. List (June 26):. The alfalfa webworm L. commixtalis Walk*, wintered 
in exceedingly large numbers, but rainy and cold weather, which occurred just 



-152- . 

after emergence started, so .divided the brood and interfered with egg laying 
that the injury is not proving to be as much" as" anticipated. However, many 
sugar beets are being sprayed- and sor.ie injury is occurring to alfalfa and certaj 
truck crops. . The sugar-beet webworm (L. sticticalis L.'. ) is appearing in 
large numbers. The injury from larva is-- just beginning to be noticeable. It 
. will be quite-general • on sugar beets in the eastern half of the state and reporl! 
indicate. that spinach, . lettuce and certain other high altitude- vegetable crops 
are going to suffer-. .:..,. 

Utah. G. E. Knowlton (June 21): Sugar beet webworm moths are becoming alarmingly 
abundant in many localities. Because of the serious injury caused last year, 
many farmers are requesting- information. . - ... 

WHITE GRUBS ( Phyllophaga spp.) 

Connecticut, W> E. Britton (June 23): Adults of P.- tristis Eab. were abundant, 
with an occasional P. fuse a Froel. feeding upon the leaves of raspberry at 
Orange . 

* ♦ - 

New York. P. M. Eastman (June 16): A farmer writes that the ground is full of the 
grubs. Potatoes are being eaten up. 

Maryland. E. N. Cory (June 22): P. futilis Lee. and P. hirticula Knoch are' attack- 
ing elms and oaks in Baltimore County. 

Missouri. L. Haseman (June 24): White grubs are less serious than usual. Eriergenq 
of beetles is fairly heavy in central Missouri. 

A. E. Satterthwait (May): The manager of Tower Grove Park, St. Louis, on May 
27 reported defoliation of sweet-gum and of pin oak trees. The sample beetles 
sent were P. micans Knoch. : . 

ASIATIC GARDEN BEETLE ( Autoserica castanea Arrow) 

New York. C. H. Hadley (June 23): The first adults en Long Island in 1933 were 
found at Jericho on Juno 19. This has been the most destructive insect in 
vegetable gardesn in Nassau County this spring, severe injury having been caused 
during May and June to many vegetables in gardens by the feeding of the larvae.-' 
Approximately 80 percent of the vegetables (including transplanted cabbage, 
peppers, and tomatoes) in a large community garden at Glen Cove were destroyed 
in suite of replantiiig efforts. The greatest injury has occurred in gardens in 
the northern half of Nassau County which were in sod last year, but several 
gardens which have been well cultivated for several years also suffered severe 
loss of vegetables. 

ASIATIC BEETLE (Anomala orientalis Waterh.) 

Connecticut. W. S. Britton (June 23): A. orientalis continues to injure untreated 
lawns. Adult beetles are now emerging. Reported at New Haven. 

JAPANESE SIRICA ( Seric a similis Lewis) 

New York. C. H. Hadley (June 23): S. similis was observed at Mill Neck, June 15 
to .19, when adults were taken in -the traps which had been placed to capture 
Japanese beetles. This gives a new distributional record for the insect. ' The 
adul'cs have been cuite abundant at lights on warm nights at Wesfcury and Mineola. 



-153- 

ROSE CHAFER ( Mac to dac tylus sub sp ino sus Fab.) 

Maine. H. B. Peirson (June): The rose chafer was stripping cornfields at Augusta 
June 17, and stripping roses June 20. It was stripping foliage of ash-leaf 
maple, blackberry, gray "birch, white birch, and willow on June 18 at Augusta, 
Portland, and Waterville. 

New Hampshire. J. G. Conklin (June 23): The rose chafer is fully as abundant as 
last year. Several orchardists report injury to young apple trees. Severe 
injury to peach trees was also recorded. 

Vermont. H. L. Bailey (June 26): Rose chafers are very abundant. Reports have 
come from Franklin and Washington Counties of particularly heavy outbreaks. 

Massachusetts. A. I. Bourne (June 24): Probably the outstanding pest of the month 
of June was the rose chafer. The first appearance in large numbers coincided 
with the hot, dry weather. The beetles were extremely active and, caused con- 
siderable damage before gardeners realized that the pest was present. It has 
attacked garden crops, small fruits, orchards (both leaves and the forming 
fruit), and many ornamentals, as well as grape: and rose. At the present time 
the attack is lessening somewhat and the beetles are beginning to disappear, but 
it has proved to be one of the most severe 'attacks which we have had for several 
years. Even in well-sprayed orchards it has not been uncommon to find them 
seriously gouging out forming fruits of apple and peach. Very often as many as 
20 to 25 of the beetles have been collected on one peach. Numerous complaints 
of the beetles attacking strawberry plantings, riddling the leaves and even 
devouring the berries, have been received. Raspberries and blackberries have 
been attacked' very severely and the pest has even been found to riddle the 
foliage of poison ivy. It might be of interest to note that in one field in 
Agawam, in central Hampden County, the rose chafer was observed early in June 
to be on the whole more destructive to the beans than was the Mexican bean 
beetle. 

Jonnecticut. W. S. Britton (June 23): M. sub sp ino sus is more abundant than usual 
on apple, peony, and rose at New Haven and Watertown. 

ffew York. p. J. Parrott (June '20): The rose chafer is very abundant from Albany 
to Buffalo. 

C. H. Hadley (June 23): The rose chafer is abundant at Westbury ,Long Island, 
especially on roses and viburnum, and conspicuous defoliation has been observed. 
In some cases 2.5 per cent of the foliage of viburnum has been destroyed. 

Cndiana. J. J. Davis (June 20): The rose chafer was damaging apple fruits at 
Evans ville, May 29. 

lichigan. R. Hut son (June 17): The rose chafer is moderately abundant. 

WIREWORMS (Elateridae) 

'ennsylvania. C. A. Thomas (May 29): The wet weather during May has been very 

favorable for wireworms. Thousands of Pheletes ngonus Say larvae were found to 
be damaging cabbage, corn, seed potatoes, rutabagas, etc., in Bucks and other 
southeastern counties, while in the western part of the State the chief injury 
wan done "ay- larvae of AgriotesVmancus Say and Meianotus sp. (June 21): Wireworr. 



-154- 

have continued to in jure , truck crops during the .wet periods of early June. A 
cornfield examined 'near Oxford; Chester County, on June 20 was about 40 per cen 
destroyed "by larvae of a species of Mclanotus ,. which were boring into the base 
of the stalks and killing the central leaves of the plants. 

North Carolina. C. H. Brannon (May 22): Wireworm damage to tobacco is reported 
over a wide area. 

Michigan. R. Eutson (June 17): Wireworms, chiefly A. mancus, are moderately 
abundant in localized areas. 

North Dakota. J. A. Munro (June 15): We have had considerable trouble with wire- 
worms in Barnes County. this last week and in many places the grain is entirely 
destroyed. Wirewoms were very injurious to iris plants at Sheyenne and at 

. - . Fargo.' Injury to corn in the vicinity of Page is serious. 

Iowa. H. E. Jaques ( June) : Wireworms are scarce in Monona, Harrison, Guthrie, 
—.Hancock, Madison, Grundy, Poweshiek, and Muscatine Counties; moderately abundan 
in crawford, Carroll, Pal'O^Alto, Union, Warren, Chickasaw, Buchanan, and Davis 
Counties; and very abundant in Osceola County. • ; - 

Alabama. K. L. Cockerham (May 31)-?: The injury to. the potato crop at Foley by 
He t erode res - lauren tii Guar., although not so severe as that of two years ago, 
has been quite general. An examination of certificates of shipping-point 
inspections showed the wireworm injury was approximately as great as the com- 
bination of all other defects,, such as decay, cuts and bruises, sun scald, grow 
cracks, ■ mechanical injury, and scab. Probably the average of injury was from 
2 to 4 percent. 

Missouri. L. Haseman (June 24): During the month a very" heavy emergence of an 
unidentified, species of wireworm occurred in central Missouri. 

MORMON CRICKET ( Anabrus simple x Hald.) 

Idaho. R. W. Haegele (June 19): The outbreak' of the mormon cricket in Bingham 

County is severe; control work has prevented damage to crops. It is occurring 
in outbreak numbers in Bonneville and Bannock Counties, and there are light 
infestations in Caribou and Elmore Counties. The insects are nearly mature, 
. except in Caribou County, where hatching did not start until early June. 

A MOLE CRICKET ( Scapteriscus acletus R. & H.) 

Texas. J. N. Roney (June 15): The golf courses of .Galveston Island are heavily • 
infested and in many instances greens have been ruined. 



CEREAL AND FORAGE-CROP INSECTS 

CORN 

CHINCH BUG ( Blissus leuc.opterus , Say) 

Ohio. T. H. Parks (June 28): An outbreak of chinch bugs occurred in Madison Count 
where the young bugs had destroyed a field of spring barley and were crossing 






-155- 

to a cornfield joining. About 1/3 of the corn was already plastered with bugs. 
This locality has suffered from drought. Today we learned of a similar outbreak 
in Delaware County .- 

Indiana. J. J. Davis (June 20): Chinch bugs are moderately abundant in isolated 
localities. They were reported as heavily infesting a barley field at Earl 
Park, June 13. .-..,■.".. 

Illinois. 17. P. Flint (June 19): In spite of the heavy rains during all the 

early part of May, sufficient numbers of chinch bugs survived to threaten injury 
over about two-thirds of Illinois. The extreme northern and southern parts of 
the State will escape injury. Many cases have been reported of fields that 
become grassy and were later plowed and planted to corn, where the bugs are now 
killing the corn. 

Iowa. C. J. Drake (June 19): The chinclv-bug situation is becoming quite serious in 
southern Iowa. The infestation includes the two southern tiers of counties from 
Page to the Mississippi River. Several fields of small grain and a few fields 
of corn have already been plowed up and planted to soybeans. In a number of 
instances the first-generation bugs are feeding in the cornfields. The present 
infestation is more serious and widespread than the outbreaks in 1924. Weather 
conditions this spring and summer have been very favorable for the chinch bugs. 

Missouri. L. Haseman (June 24): Chinch bugs are doing considerable damage to wheat, 
oats, and barley, ' moving to corn last. The infestation is worst in the north- 
central part of the State. 

Nebraska. M. H. Swenk (June 20): The center of greatest abundance seems to be 

Lancaster and Saline Counties, but the bugs are more than ordinarily plentiful 
over much of southeastern and southern Nebraska. A report from as far to the 
northwest as Boone County indicates that they were locally abundant there. 
Owing to the early drying-up of the barley and oats, the migration started 
shortly after the middle of June, which is earlier than usual in this locality, 
and was at its height on June 20. Considerable damage to corn will undoubtedly 
result from the chinch bug depredations. 

Kansas. H, R. Bryson (June 22): Chinch bugs are more injurious at Manhattan and 

surrounding territory than they have been since 1927. A considerable infestatio 
occurs in corn and sorghum fields as a result of old bugs laying eggs at the 
bases cf the corn plants. Migrations from the small-grain fields to the corn 
and sorghums began about ten days earlier than normal. This condition was 
occasioned by the hot, dry weather, which hastened the maturity of wheat, oats, 
and barley. Counties in the eastern part of the State, which have received 
heavy rains during May and the first part of June, have less injury. Reports 
of injury have come from Canton, Ueridgh, Howard, Willard, Elk Palls', and 
various points in the vicinity of Manhattan. 

Oklahoma. C. F. Stiles (June 13): Chinch bugs are still very numerous in' the east- 
central part of the State, with the center of infestation at the present time 
around Sapulpa, in Creek County. Some of. the sweet corn in the city gardens 
located near wheat fields are being destroyed by chinch bugs migrating from thes 
fields. Com and other row crops are being heavily infested by migrating chincr. 
bugs, in 10 counties at the present time. 



-166- 

Texas. F. L. Thomas (June 21): Chinch hugs were abundant and injuring sudan grass 
at Waco on June 8. ..•■..'. 

LESSER CORN STALK BORER ( Elasmopalpus lignosellus Zell.) 

Georgia. J. M. Ingram (June 2): The lesser corn stalk "borer was found to be 
causing quite a bit of injury to sugarcane at Cairo. 

G. K. Eiror (June): E, lignosellus has caused commercial damage to the corn 
crop of southern Georgia. ••■■■.■. 

Florida. E. S. Chamberlin (June 10): The lesser corn stalk borer occurs in injurs 
abundance throughout Gadsden County. Late-planted corn is sustaining the most 
damage, which in some instances amounts to a complete loss. 

J. R. Watson (June 28): Daring late May, particularly, there was heavy outbreak 
throughout all northern Florida from Marion County north and west. Damage was 
chiefly to corn, especially late-planted corn, but; cane was injured, also. 
Injured, corn is still breaking off with every heavy wind. In, some fields in 
Alachua County the loss was as high, as 75 per cent of the crop. Where corn was 
planted after a crop of Irish potatoes, even although the corn was late there 
was no injury. 

Alabama. J. M. Robinson (June 21): We have had a considerable outbreak of the 

lesser corn stalk borer and also the larger corn stalk borer ( Diatraea c ramb i d - 
o ide s Grote) from the following counties: Morgan, Sumter, Chilton, Lee, Loundes 
Clarke, Washington, Conecum, Covington, Geneva, and Henry. It has been quite 
active in Southern and Central Alabama where from 5 to 50 per cent of the crop 
is damaged, and is also reported from the Tennessee Valley. Apparently the 
corn is receiving more damage from the lesser corn stalk borer than the larger.. 
However, it is not unusual to have corn sent in with the larvae of both insects 
in the sane plant. 

K. L. Cockerham (June 8): The lesser corn stalk borer was doing considerable 
damage to field peas at Delchamps, Mobile County, on June 8. Many plants were 
being killed. 

Louisiana. W. E. Hinds (May 29): The lesser corn stalk borer occurs in many field* 
of corn in eastern Louisiana. 

Mississippi. C. Lyle (June 22) : Probably no insect attracted as much attention in 
Mississippi during the past month as did the lesser corn stalk borer. Severe 
injury to young corn was reported from a large number of counties in the south-^ 
era half of the State. 

CORN EAR WORM ( Heliothis obsoleta Fab.) 

New Jersey. T. J. Headlee and R. C. Burdette (June 23): The corn ear worm is very 

abundant. 

Missouri. L. Haseman (June 24): At Columbia a .-few corn ear worms have appeared in 
pea pods and some in tips of early corn plants, ;-■ 

Alabama. K. L. Cockerham (May 29): At Foley on May 29 green corn harvested for 
early shipment was very severely damaged. Fully 50 per cent of the corn was 
rejected at the packing sheds and approximately 99 per cent of all ears showed 
injury. This is the heaviest damage noted in several years. The varieties

ALFALFA 

ALFALFA WEEVIL ( Hype fa postica Gyll.) 

Utah. G. F. Kn owl ton (June 24): The alfalfa weevil is moderately to very abundant 
in central and northern Utah. Damage is apparent in many parts of Utah, and 
much of the alfalfa has been cut to stop the injury. 

Nevada. G. G. Schweis (May): Damage was somewhat spotted throughout Nevada. In 
some sections control measures were necessary, while in other parts weevils ' 
were not at all numerous, and even scarce. 

California. A. E. Michelbacher , ( June 19): The alfalfa weevil populations in the. 
various districts are low. For the most part all over middle California the 
alfalfa has been cut the second time. In the Tracy area the weevil is very

CODLING MOTH ( Carpo-capsa pomonella L.) 

New York. P. J. Parrott (June 20): The codling moth is very abundant in western 
New York. 

N. Y. State Coll. of Agr, News Letter (June): Hot weather during the second 
week in June accelerated egg hatching in both the Hudson River Valley and 
western New York. Otherwise conditions seem about normal. (Abstract, J.A.H.) 

Delaware. L. A. Stearns (June 23): Spring-brood emergence is about ended;' first- 
brood injury is generally much lower than that of 1932, 1931, and 1930. 

Pennsylvania. H. N. Worthley (June 8): At Biglerville, Adams County, larvae were 
first seen entering the fruit on May 28, and fresh entry was noticeable during 
the first week in June. .High temperature is causing rapid emergence of moths. 
The 50 percent point of overwintered brood emergence was passed during the first 
week in June. 

Ohio. C. R. Cutright (May 29): Emergence in orchards at Wooster started about 
normal while cage emergence did not start till a week later. Owing to warm 
weather the emergence has been rapid, with moths quite active. . 

Indiana. J. J. Davis (June 19): " The codling moth is very abundant in southern 
Indiana. 

/Illinois. W. P. Flint (June 19): The codling moth is more abundant in most 

orchards than at any time during the past 20 years. The weather on the whole 
has been favorable for first-brood development. Larvae are now going under 
bands throughout the southern two-thirds of the State. Second-brood hatching 
is expected in the Johnson, Union, Jackson County areas July 4-5, with con- 
siderable numbers of worms hatching by July 7-8. In the south-central part of 
the State the first hatch will occur in the Flora, Olney, Salem, southern 
Calhoun County sections July 6-7, with hatch, in numbers by July 10-12. In 
central Illinois in the Adams, Logan, DeWitt, Vermillion County areas the first 
hatch will be about July 10-11, with a considerable hatch by July 13-14. The 
first-brood infestation is very heavy in many orchards, and, because of the 
light crop and scabby condition of the fruit, it 'will be necessary to spray 
very tho-»oughly in order to control second-brood wo mis. 

Wisconsin. C. L. Fluke (June 19): Codling moths are moderately abundant. The 
first heavy flight of adults occurred -June "9 and 10. Not so abundant as last 
year. 

Missouri. L. Haseman (June 24): Indications are that we will have heavy broods 

of late worms. Moths of the second brood are beginning to emerge in .the. south- 
ern part of the State. Pupating June 24 at Columbia and in northern Missouri. 

Oregon. D. C. Mote (June 14) : The peak of egg laying was reached June 12. Egg 
laying' is late because of prolonged wet weather. ..; •;.:.' : ■- ••

emergence "but by June 19, following a week -of warm weather, a considerable 
number of moths had emerged. It now looks as though the brood would be heavy 
but spread out, and, owing to hardening of the walnut shells as summer advances 
the injury may be comparatively slight. The development of the codling moth in 
apples and pears in the Antelope Valley has also been, delayed* The fruit crop 
is light, owing to spring frosts.

cherries. At the present time they have generally left their webs and have gone 
to other plants and down to the ground-. 

West Virginia. L. M. Peairs (June): The eastern, tent caterpillar is very abundant 
in northern West Virginia. Webs still show at high elevations. 

Virginia. R. A. St. George (May): The extent of defoliation is not regarded as 
being severe, so far as the area is concerned, but individual trees were often 
found completely stripped. -The insect was present along both sides of the 
mountain, where it confined its activity to defoliating apple and wild cherry 
trees. The tents were quite conspicuous in central Virginia.

APPLE MAGGOT ( Rhagoletis pomonella Walsh) 

Massachusetts. A. I. Bourne (June 24): According to Professor Fnitcomb, the 

first emergence occurred at Waltham on June 22. This would tend to indicate 
that the flies will probably be appearing in the orchards at the normal time 
or possibly earlier. 

New York. N. Y. State Coll. of Agr. News Letter (June): Apple maggot flies have 
been reported emerging in Orange County since June 10. They were observed on 
Red Astrachan June 14 in Dutchess Counts'. The first flies were observed in a 
Jonathan orchard at Milton, Ulster County, on June 12. Since then, more have 
been seen in other parts of the county. 

ROSE LEAF BEETLE ( No do no ta puncticollis Say) 

Connecticut. M. P. Zappe (June 21): Beetles are very abundant, attacking a number

Connecticut. W. E. Britton (June 23): The oriental fruit moth is moderately 
abundant . 

Hew York. N. Y. State Coll. of Agr. News Letter (June): During the last week in 
May and the first week in June larvae were observed in the terminals of peach

PEACH BORER ( Aegeria exitiosa Say) 

larvae at Fort 
Georgia. 0. I. Snapp (June 16): A couple of days this week were spent collecting 
•Valley for the season's life-history work. Not a single full-grown larva was ; 
taken nor did we find any pupae. This collection involved the examination of 
many trees and is therefore further proof that under natural conditions the 
pea.cn borer does not begin to pupate in this locality until late in June. 

North Dakota. J. A. Munro (June 15): This is -the predominating species of borer i 
plum trees at Mandan, Morton County.

species is abundant at Fargo. 

PLUM CURCULIO ( Conotrachelus nenuphar Hbst.) 

New York. N. Y. State Coll. of Agr. News Letter (June): -Damage was quite severe in 
iflas Hudson River Valley during the early part of the' the month. 

New Jersey. T. J. Keadlee and R. C. Burdette (June 23): The plum curculio is very 

abundant. 

Delaware. L. A. Stearns (June 23) : Emergence of first-brood adults is just 
commencing. There is considerable parasitization. 

Georgia. 0. I. Snapp (June 5): At Fort Valley the emergence of first-generation 
adults from the soil started on May 27. This is 20 days earlier than the first 
emergence date last year, and 19 days earlier- than the first emergence date of 
1931. A second brcod of larvae is assured. The peak of first-generation adult 
emergence occurred this year on June 1. (June 20): Although first-generation 
adults have been emerging since May 27, there has not been any second-generation 
egg deposition to date. Emergence was heavy in the orchards during the week 
ending June 16, and we are expecting second-generation eggs before the Hileys 
are picked. A total of 39,535 larvae were reared from 8 bushels of drops 
collected near Eort Valley. There are about 8,000 drops in each bushel. This 
record does not represent the average infestation in this locality this year, 
but more nearly the maximum infestation, as the drops came from an orchard in 
which no spray or dust had been applied or other curculio control measures 
enforced before the drops were picked up. Furthermore, the infested peaohes 
that fell during harvest last year were not removed from this orchard. (June 
27): Second-generation egg deposition began today. 

W. H. Clarke (June 9): The first adults of the first brood emerged from the 
soil at Thomaston toda.y. 

Ohio. E. \7. Mendenhall (June 2): At Columbus the plum curculio is very abundant 
on sour cherry fruit, causing considerable damage.

sections. 

Missouri. L. Haseman (June 24): Larvae have been leaving the fruit during the last 
10 days. The infestation is less serious than usual. Stings on apples are 
abundant. Some larvae have just hatched. 

Tennessee. H. G. Butler (June 15): The first brood of the curculio began emerging 
at the insectary at Harriman June 13. This is 8 days earlier than emergence 
started in 1932 and 6 days earlier than any previous record during the last 4 
years.

and 

San Juan Plant Quarantine Office 



COCCIDAE 



The citrus mealybug, Pseudococcus citri Risso, was exceptionally abundant 
during the first half of June in citrus groves in the Bayamon district despite 
reasonably rainy weather. (G. N. Wolcott.) 

Some months ago Pseudococcus nipae Mask, was noted so abundant on one avocadc 
tree in Rio Piedras, covering all the twigs and much of the larger branches, as 
to cause its complete defoliation; but the insects shortly afterward disappeared 
and the tree now appears normal. At about the same time the mealybug was very 
abundant on guava bushes and still continues to be rather common. I am of the 
opinion that this may be one of the delayed results of the hurricane, destroying 
the introduced ladybeetle Cryptolaemus montrouzieri Muls., none of which has 
been seen since. (G.N.W.) 

The cottony cushion scale, Icerya pure ha si Mask., has spread a few miles 
farther to the southwest, being reported in the Bayamon district on the Comerio 
Road, and in the Espinosa district, between Dorado and Vega Alta. The lady- 
beetles have practically cleaned up most large infestations in San Juan, Santurce 
the Bayamon district, and Dorr-do, and have been found in the new infestations of 
the scale, having reached these by their own efforts. About 2,500 beetles were 
distributed this spring and have done good work except in small infestations 
and in exceptionally wind-swept locations. (G.N.W.) 

ALEYRODIDAE 

The woolly white fly of citrus, Aleurothrixus howardi Quaint., is ordinarily 
so scarce in Puerto Rico that infested leaves are curiosities, and never have 
I found more than one at a time. In a citrus grove between Bayamon and Toa Baja, 
observed rather carefully recently, a dozen or more infested leaves per tree were 
noted on several trees. The owner reports having had his majordomos from this

THE MORE IMPORTANT RECORDS FOR JULY, 1933 

In addition to reports of generally severe grasshopper infestation occur- 
ring in the Great Plains we have reports of very heavy infestation in the upper 
and lower peninsulas of Michigan, the northeastern- one third -of Wisconsin and 
two outbreaks in California, one in the Imperial Valley and the other in the 
San Francisco Bay district. The infestation in the Mississippi Delta continued 
severe during July and several carloads. of bait were distributed in that dis- 
trict. In northeastern Nebraska 18 carloads were used. We- do not have defi- 
nite figures for the quantity of bait used in the Dakotas and Minnesota where 
the heaviest control campaign is under way. 

Serious < chinch- bug outbreaks are under way in eastern Kansas, northern 
Missouri, southern Iowa, central Illinois and Indiana,, southern Michigan, and 
western Ohio. In Illinois and Ohio infestations are reported as more severe 
than they have been in years. 

The green June beetle is unusually prevalent this year in- Ohio, Missouri, 
and Tennessee. 

Very heavy infestations of the Colorado potato beetle- are reoorted from 
New England, Wisconsin, Minnesota, North Dakota, eastern Tennessee, and east- 
ern Wyoming. In the West these beet! es are decidedly more numerous than they 
have been before in the Yakima Valley of Washington and an infestation cover- 
ing a few square miles near the Weber- Davis Count3 r line has been discovered in 
northern Utah. 

Very heavy infestations of the potato leafhopper with the resulting hop- 
per-burn injury a»e- reported from the Middle Atlantic States from Connecticut 
to Virginia and westward to Iowa and Minnesota. 

The potato tuber worm has been found in a number of potato fields in 
central Iowa. This is the first record we have for the State of Iowa and the 
first record of its being established in potatoes in the Central States. 

The Mexican bean beetle was found far to the northwest of its known dis- 
tribution in the St. Paul - Minneapolis district of Minnesota. This is be- 
lieved to be a commercial jump and extermination is being attempted. 

The gladiolus thri'ps was reported for the first time during July in eas- 
tern Iowa' and Delaware. •'•'■.'' .. \. ; ,-..••..

GENERAL FEEDERS 

GRASSHOPPERS (Acrididae) * ■ r •■ : 

Michigan. Ray Hut son (July 22) : Grasshoppers are very abundant in the upper 
.peninsula and the northern part of the lower peninsula. 

Wisconsin. E. L. Chambers (July 24): Very serious damage lias occurred in about 
30 counties of northern Wisconsin, principally : the northeastern third. Near- 
ly 100 tons of white arsenic was used in baits in addition to several car- 
loadsof molasses and many carloads of bran. 

Minnesota. A. 0. Rugbies (July 15): We are controlling grasshoppers remarkably 
well in spite of ideal weather for the hoppers. The prediction made last 
December was 99 per cent correct. 

North Dakota. J. A. Munro (July 22): Reports indicate that various species of 
grasshoppers are very abundant over most of the area previously reported as 
infested. Where control was begun early, successful poisoning campaigns 
have resulted. Eggs are now being deposited by Melanoplus bivittatus Say, 
M. mexicanus Sauss», and Camnula p ellucida Scudd. 

R. .1. Olson (July 17); Strong grasshopper flights high in the air were 
notecVon July 9, in Bowman County, all going southeastward. 

Mississippi. C. Lyle (July 21): Several scattered outbreaks of grasshoppers, 
chiefly M^ diff erentialis Thos., in the Mississippi Delta were reported dur- 
ing the past month. Serious damage, continued on several thousand acres of 
corn, soybeans, and cotton at Parchman until the application of several car- 
loads of poisoned bait gave control. 

Nebraska. R. Roberts (Julj? - 20); Grasshoppers have been very abundant in the 
northeastern part of the State. A state-aided control campaign has been 
in progress for over a month, 18 carloads of poisoned bran mash have been 
distributed, and good kills have been reported.: Reports have also been 
received from Douglas, Saline, and Harlan Counties. 

Wyoming. C. L. Corkins (July 2l) : Grasshoppers are very abundant. A severe 
outbreak developed during earl" July in Crook County. The valleys are 
infested with M^ bivittatus , and the grazing lands in the hills have a 
mixed infestation of any species, which are now migrating to the valleys. 
Certain sections of Sheridan County have serious troubles. Minor outbreaks 
have developed in -Fremont, Johnson, and Weston Counties. 

Utah. G-. f, Knowlton (July 11): M^ bivittatus is damaging sugar beets, straw- 
berry plants, and black-cap raspberries at Hooper. Grasshoppers are damaging 
alfalfa and grain on the ranches in Skull Valley, particularly at Iosepa. 
Large numbers of IL_ mexicanus are becoming adult in mazr' parts of Tocelc 
County and are causing serious damage. to crops at Grantsville. (July 21): 
Grasshoppers completely destroyed a 3-acrc sugar-beet patch, then advanced 
upon wheat and barley during June, in the low area west of Provo. 

California. A. E„ Michelbacher (July 20): In at least one area near Tracy the 
differential grasshopper, M. dif f erentiali s, is rather abundant. I have 



-189- 

watched the development, and at the present' time a large number have reached 
• the . adult stage. 

Evening Star, Washington, D. C. (July 26): The worst grasshopper plague in 
17 years is being experienced by Imperial Valley. Desperate in. their efforts 
to destroy the pest, farmers plan to import pheasants in the hope that the 
birds will eat the hoppers before the second crop sprouts wings. Grapefruit 
have been devoured by the thousands. 

WHITE GRUBS ( Phyllophaga spp.) 

Illinois. W. P. Flint (July 22): Serious damage from white grubs is beginning 
to show in cornfields in northern Illinois. 

Wisconsin. E. L. Chambers (July 24): Serious losses from white grubs are being 
reported by nursery inspectors and other field men in some of the southern 
counties. 

Iowa. H. ?. Jaques (July 24): The area of serious infestation in northwestern 
Iowa seems to be enlarging to the east. The abundance in other parts of the 
State seems less than normal for this brood. 

Missouri. L. Easeman (July 25): Only the usual number of white grubs at this 
season in central Missouri; though in sotrthern Missouri one orchardist 
reported defoliations of apple recently. : 

GREEN JUNE BEETLE ( Cotinis nitida L. ) 

Ohio. IT. F. Howard (July 10): Adults were present in large numbers on sweet 
corn and cucumbers at Marietta on July 8. They were so numerous as to 
resemble a swarm of large bumble bees. 

Missouri. L. Haseman (July 25): At Columbia the green June beetle was quite 
abundant for a few days, July 15 to 20. 

Tennessee. G. M. Bentlcy (July 22): Green June beetles were very abundant in 
the Cumberland Plateau section and Knox County. 

JAPANESE BEETLE ( Popillia japonica Newm. ) 

General. C. H. Hadley (July 24): In the older infested territory the Japanese 
beetle is less abundant than last year*. This is especially true in the 
Philadelphia suburban region. In the more recently infested territory the 
beetle is abundant and feeding extensively on the usual preferred food plants. 
In addition to those plants, the beetle is this year -feeding on alfalfa, 
clover, and beans. It has also been causing, for the first time, considerable 
injury in nursery plantings to evergreens, especially Cryptomaria and juniper, 
as well as to rhododendrons and azaleas. The insect has also been reported 
as feeding extensively on a cultivated banana plant in a yard at Moorestown. 
-•- -Feeding on waxmyrtle ( Hyrica carolinensis ) ha,s been extensive at the Wild- 
wood Golf Course at Burleigh, jr. J. 

New Jersey. Headlee and Burdette (July 24): The Japanese, beetle is very abun- 
dant.

Delaware. I. A. Steams (July 22); The Japanese "beetle is reported in northern 
Delaware — Wilmington and vicinity; the infestation is severe, on the in- 
crease, and spreading southward. 

District of Columbia. A. N. Caudell (July 10): The Japanese beetle was found at 
the corner of Keefor Place and 6th Street, N, W. , Washington. It may be found 
common all over our neighborhood now. 

ASIATIC GARDEN BEETLE ( Autoserica castanea Arrow) 

New York. C. H. Hadley (July 24): This beetle is more abundant on Long _ Island 

this year than it was in 1932. Reports of injury have been received from smal 
property owners as well as from large estates in the infested region. Exten- 
sive damage, to such ornamental plants as chrysanthemums, asters, orchids, and 
dahlias is common, and in gardens the feeding is heavy on cabbage, eggplant, 
and peppers. 

COMMON RED SPIDER ( Tetranychus telarius L. ) 

Georgia. 0. I. Snapp (July 12); Weather has beer, dry and hot and red spiders 

are more abundant than usual at Marshallville, causing considerable damage to 
yard plants.

field station at Monticello, the red spider T^ t elarius is doing considerable 
damage to foliage of pecans in that district. 

Indiana. J. J. Davis (July 26): ■ -The red spider was heavily infesting Colorado 
blue spruce at Valparaiso June 20. During the past month it has also ^een 
abundant on evergreens and phlox at Lafayette,

Sunflower Counties. One report of a heavy infestation on cotton was receivedi 
from Le Plore Count3 r . 

Nebraska. R. Roberts (July 20): A report w?,s received the latter part of June 
from Keith County, stating that the red spider was attacking a Black Hills 
spruce tree. A Douglas County correspondent reported it working on a willow 
tree.

Goodyear, Cumberland County. 

Ohio. T. H. Parks (July 13): We are having, the worst infestation in many years. 
May was rainy; June was dry. Bugs have destroyed many plantings of barley 
in Madison, Union, and Delaware Counties. They began moving out of barley 
and wheat fields the last week of June and were still moving July 13. One 
gas company has already sold 5,000 gallons of tar for making barriers. Madi- 
son County shipped in several carloads of tar. Miles of. tar lines have been 
made and as many, dust barriers. A few fields of corn were ruined before the 
farmers were aware of the bugs. The area affected is mainly in the west- 
central counties. Reports of damage have reached us from 14 counties. 

Indiana. J. J. Davis (July 25): The chinch bug lias been an outstanding problem 
in many sections of the State. There are two centers of infestation. One in 
the northwestern corner includes Newton, Benton, Lake, and lAPorte Counties. 
The other is in the northeastern part of Indiana and includes the counties of 
Jay, Adams, Allen, Steuben, Wells, Elkhart, and Blackford. Reports of in- 
festations in small grain or migrations from small grain to corn have been 
reported from the above areas throughout the month. June 29 the bugs were 
moving from barley and oats into corn at Fowler. Apparently barley is the 
source of the heaviest infestations. 

Illinois. W. P. Flint (July 22): During the past month the chinch bug has been 
the outstanding crop pest in the State. Spotted heavy damage has occurred 
from Randolph, Montgomery, Clay, and Jasper Counties on the south to Rock 
Island, Henry, Lee, DeKalb, Kane, and Cook Counties on the north. The first 
brood has now matured and a general flight has taken place over the cornfields. 
The weather is so dry that the second brood will probably cause serious 
damage throughout the heart of the Illinois corn belt. From present indications 
it is possible that the bugs may cause a, loss of 25 per cent of the corn crop 
in this area. " 

Michigan. R. H. .Pettit (July 12): I have just received word that chinch bugs

some injury was done in the third tier of counties. At the present time the 
adults of the first generation are depositing their eggs and the young of the 
second generation are beginning to appear in considerable numbers. 

Missouri. L. Ha soman (July 25): Infestation has been^ general and in some places 
very heavy over the northern half of the State. The bugs are most abundant 
northof the Missouri River and near the Iowa line.

Riley, Geary, Marion, Dickinson, Butler, Sedgwick, and Chase Counties revealed 
chinch bugs being quite destructive to corn and sorghums and adjoining fields 
of small grains. Dry weather was favorable to the bugs in their attack on the 
row crops. Reports of injury have also been received from Wabaunsee, Cloud, 
and Miami C o unties.

INSECT ?--3 ST SUHSY BULLETIN 



K I 



Vol. 13 September 1, 1933 No. 7 

THE MOLE IMPORTANT HEC0EDS 1GR AUGUST, 1933 

The grasshopper situation in the Northern Plains States continued serious 
through August. Populations are heavy over much of this territory and unless 
unfavorable weather conditions prevail next spring the outlook for destruction 
by grasshoppers next year -dbs more serious than it has been any :]^ejvio i im:ysia¥*(5f r 
the present outhreak. Outside of this most heavily infested territory grass- 
hoppers were reported as unusually abundant in parts of Virginia, Oklahoma, 
Nevada, Arizona, and Utah. 

Important infestations of mormon crickets were reported from parts of 
Montana and isolated localities in Nevada, Utah, and North Dakota. 

The fall armyworn appeared late in the month in Arkansas, Mississippi, and 
Texas. In Mississippi heavy damage was reported from several sections of the 
State. 

Brood- -A of the white grubs was rather heavily infesting pastures in Indiana, 
Wisconsin, Minnesota, Iowa, and Missouri. 

The Asiatic garden beetle was more abundant this year and injury much more 
extensive than during any previous season in the New York - New Jersey area. 
Another scarabaeid, Serica similis Levis, was taken for the first tine at Mill 
Neck, F. Y. 

In this number of the Survey Bulletin are summaries of the Hessian fly sur- 
vey in Ohio and Illinois. The infestations are puck lighter than last year, 
being 8 per cent in 1933 and 34 per cent in 1932 in Ohio, and 3.76 per cent in 
Illinois in 1933 and 29 per cent ir. 1932. 

The chinch bug appeared during the month in large numbers in parts of New 
England and Pennsylvania, far east of its normal habitat. It also continued to 
be unusually abundant north of the chinch 'our-; belt in Michigan, Minnesota, and 
Iowa. Within the chinch bag bolt heavy populations -ere appearing from Ohio to 
Missouri indicating large numbers of bugs to go into hibernation and the possi- 
bility of outbreaks next year. 

The corn ear worm was quite generally reported as destructively abundant a * 
throughout practically the entire territory east of the Locky Mountains, Along 
the Middle Atlantic -and South Atlantic seaboard damage was quite generally severe. 

-223- 



-224- 

The lesscrcorn stalk "borer was heavily infesting corn fields fron eastern 
shore Virginia to Florida, in United areas the entire stand of late sweet corn 
being destroyed. 

The corn leaf aphid was damaging corn locally fron Kansas to Michigan. 

Late worn injury "by codling moth was quite generally reported fron the 
Middle Atlantic and South Atlantic States westward to Missouri and Kansas. 

Heavy rains which occurred over nuch of the area infested "by the oriental 
fruit noth produced new succulent growth favoring twig infestation over un- 
usual periods. 

In the South Atlantic peach belt plun curculio danage was decidedly subnor- 
mal. Sinilar light infestation was reported fron Arkansas. 

In the grape— growing section of Michigan there was a very heavy infesta- 
tion of the grape berry noth. 

The occurrence of vinegar flies, Drosophila spp. , in cannery tonatoes along 
the Atlantic seaboard was occasioning considerable alarn anong canners as the lar*i 
vae infest the tonatoes before canning. 

The Mexican bean beetle was quite generally reported abundant throughout 

the Hew England, and Middle Atlantic States, while in the South Atlantic, and 

East Central States it was less abundant than last year. Heavy infestations 
were reported fron Colorado and Slew Mexico. 

The onion thrips was nuch nore abundant than it has 'oeen for several years 
in the Connecticut Valley of Massachusetts and Connecticut. 

ELn leaf beetle was reported during the month as browning foliage in nany 
localities in the Hew England and Middle Atlantic States southward to Maryland 
and westward to Ohio. 

Outbreaks of screw worn fly were reported fron parts of southern Georgia 
and northern Florida this year. There are no previous reports of outbreaks of 
this insect in this region.

GENEEAL FEEDERS 

GEA.S SHOPPERS (Acrididae) 

Virginia. The Evening Star, Washington, D. C. (July 15): A farmer on the Spring 
Hill road, near Staunton, reported that grasshoppers have practically destroy- 
ed three fields of clover and tnat huge swarms are infesting farms in that 
section, cutting off the growth on an 18-acre two-field planting of new clover 
at the ground. Reports have also come that grasshoppers have attacked 
timothy hay and have spread to gardens and elsewhere in that vicinity. 

Illinois. W. P. Flint (August 22): Very little grasshopper damage is reported 
from any part of the State. 

Kentucky. M. L. Didlake (August 25): Grasshoppers are very abundant. There are 
complaints of injury to dahlias and zinnias everywhere around Lexington. 

North Dakota. J. A. Munro (August 21): A survey made through Cass and Richland 
Counties August 8 and 9 showed that Melanoplus "bivittatus Say constituted 
about 20 per cent of the injurious species; the balance consisted largely of 
M. mexicanus Sauss. and Camnu la peliucida Scudd. In 1952 the distribution of 
species differed in that M. b ivittatus constituted between 85 and 90 per cent 
of the population and the balance were other injurious species. 

Iowa. H. E. Jaques (August 23): Grasshoppers are unusually scarce in most of 
the State. 

Minnesota. A. G. Ruggles (August 21): Egg laying in process. The weathrr is 
ideal for grasshoppers. No appreciable crop loss has been reported. One 
hundred carloads of bait have been used, as compared with 500 last year, 
showing that the 2 years of campaign kept grasshoppers under control. 

Wisconsin. E. L. Chambers (August): Grasshoppers are very abundant in northern 
and central Wisconsin. 

Tennessee. G. M. Bentley (August) : Grasshoppers are scarce. Relatively fewer 
individuals than normal are present at this time. 

Oklahoma. C. F. Stiles (July 27): Grasshoppers are quite numerous in some places 
in the southwestern part of the State, but I have been unable to check up on 
the damage to date. They are moderataly abundant in western Oklahoma. 

Nebraska. M. H. Swenk (August 21): Grasshoppers are moderately abundant, mostly 
in central Nebraska. Reported from Greeley, Dawson, and Lincoln Counties 
during the period July 20 to August 21. 

Montana. A. L. Strand (August 19): The migratory grasshopper, M. mexicanus , has 
increased this year to outbreak numbers over large areas, especially in north- 
ern and eastern Montana. About 50 counties are facing severe outbreaks for 
the coming season. 

Colorado. G. M. List (August 24): The grasshopper infestation has been rather 
spotted, there having been no really serious outbreaks, but the infestation 
in the foothills region east of the mountains, is heavy enough to call for 
considerable control work. 



-226- 

Nevada. G. G. Schweis (August 21): Grasshoppers of several species have "been 

troublesome in widely scattered areas in Nevada, doing much damage to alfalfa 
and ^rain. Control measures were necessary in some instances, and the hoppers 
took the bait readily, resulting in a good kill. 

Utah. G. F. Knowlton (August 18): Grasshoppers are damaging young fall wheat at 
Mt. Pleasant and Minersville. 

Arizona. C. B. Lebert (August 26): The pest of primary concern this month is 
grasshoppers. We have had the most severe infestation this year that has 
ever been recorded in this State. M. mexicanus was observed early, in fact 
as early as April this hopper was observed mating in the fields. Consequent- 
ly, during the last half of May and extending well into the month of June 
there was a very heavy infestation of this species in the Salt River Valley. 
Drastic control measures were immediately put into effect. But beginning the 
latter part of June and extending through July the large differential grass- 
hopper, M. diff erentialis , became very abundant in practically all areas of 
the Salt River Valley, especially in the Glendale, Laveene, South Tempe, and 
Mesa areas. Then at the peak of the differential grasshopper development 
another brood of M. mexicanus became abundant. Several fields of cotton 
have been completely destroyed, as well as several plantings of hegari. 
Many alfalfa fields have been stripped and much garden stuff has been ruined. 

Hew Mexico. J. R. Syer (July 24): M. femur- rub rum DeG. is moderately abundant 
in the northeastern part of the State. 

Oregon. D. C. Mote (July 25): M. saltator Scudd. was reported as damaging a 
mint field at Jefferson July 10. 

EASTERN LUBBER GRASSHOPPER (Romalea micro? tera Beauv.) 

Georgia. W. H. Clarke (July 26) : Thousands of lubber grasshoppers were observed 
between 311 i jay and Talking Rock on State Highway No. 5. Many had been kill- 
ed by cars. 
J. B. Gill (August 22): Lubber grasshoppers are moderately abundant at Tifton 

Mississippi. C. Lyle and assistants (August): Lubber grasshoppers are moderately 
abundant at Ocean Springs. 

MORMON CRICKET (An abrus simplex Hald.) 

North Dakota. J. A. Munro (August 21): Many specimens have been received from 
various parts of the State, with one report of crop injury from Burke County. 

Montana. A. L. Strand (August 13): Important infestations occur in four 

different sections of Montana as follows: Pryor Mountains and Wolf Mountains 
in Big Horn County; Dry head district in Carbon County; Sanders and Lake 
Counties; Little Rockies in Blaine and Phillips Counties. The Pryor 
Mountain, Wolf Mountain, and Dryhead infestations are by far the most importan 
and a campaign against the crickets is being organized for next season. 

was 
Nevada. G. G. Schweis (August 21): An infestation/reported from the Utah-Nevada 

line, but this report has not been confirmed by this office. 



-227- 

Utah. G. F. Knowlton (July 22): A small outbreak is reported from Rich County. 

FALL ARMY WORM ( Laphygma frugiperda S. & A.) 

Arkansas. D. Isely (August 23): Scattered infestations appeansAc in northwestern 
Arkansas in early August. As yet there has been little injury. 

Mississippi. C. Lyle (August 23): Severe injury to young corn at Poplarville, 
Pearl River County, was reported on July 26. Since that time, reports of 
heavy damage to young corn have been received from several sections of the 
State. During the past few days specimens or authentic reports regarding 
their occurrence have been received from Lincoln, Sunflower, Monroe, and 
Oktibbeha Counties. 

Texas. F. L. Thomas (July 29): Grass -worms appeared very scatteringly at College 
Station on July 22. 

VELVETBEAN CATERPILLAR ( Anticarsia gemmatilis Hbn.) 

Florida. J. R. Watson (August 24): The velvetbean caterpillar appeared in Polk 
County in July and in Alachua County in early August. It is not as yet very 
abundant in the latter county. 

MITE GRUBS ( Phyllophaga spp.) 

Indiana. J. J. Davis (August 29): White grubs were reported very abundant in sod 
at Hobart, July 30. 

Wisconsin. E. L. Chambers (August): White grubs are very destructive to corn, 
oats, and pasture lands in the southeastern part of the State from Marinette 
County southward through Waushara County to Vernon County. 

C. L. Fluke (July 25): Brood A white grubs are doing considerable damage to 
pastures in southwestern Wisconsin; Population studies show from 200,000 to 
800,000 per acre. Larvae of brood C pupated by the middle of July. 

Minnesota. A. G. Rugbies (August 21): White grubs are very abundant. 

Iowa. H. E. Jaques (August 23): White grubs are showing up and causing severe 
damage to lawns, pastures, etc., in some localities in the areas usually 
harboring brood A. 

Missouri. L. Easeman (August 23): White grubs are abundant, and moles have been 
doing serious damage to crops while seeking for and feeding on them. 

GREEN JUNE BEETLE ( Cotinis nitida L.) 

Georgia. W. H. Clarke (July 18 to 28): Green June beetles were numerous about 
home orchards near Athens, Gainesville, Cleveland, Morganton, Lafayette, and 
Bremen. No serious injury was noted. 

JAPANESE BEETLE ( Popillia .laponlca Newra.) 

New Jersey, Pennsylvania, and Delaware. C: H. Hadley (August 22): Adults in 

the more heavily infested sections of New Jersey, Pennsylvania, and Delaware 



-1228- 

decreased rapidly at the end of July, and in August were reduced so much that 
relatively little, if any, damage to vegetation appears to have "been done. 
Compared with most years, the infestation this summer was quite light in most 
places. Larvae which hatched from eggs laid during the present season appear 
to be of about the same numerical strength as at the corresponding time last 
year. Rainfall during the present summer has been copious and has provided 
conditions much more favorable to larval survival than was the case in the 
summer of 1932, when the prevailing drought appears to have been. the prime 
factor in reducing the adult beetle population to the low point witnessed this 
year. The importance of wind as a factor in promoting the spread of the 
Japanese beetle was emphasized by the discovery of numerous beetles washed up 
.along the south shore of Long Island as far east as Fire Island. As far as 
known, these beetles were all dead. Large numbers of beetles were also found 
washed up along the south shore of Delaware Bay, of which some were alive. 
This observation shows that a body of water as wide as Delaware Bay would be 
only a partial obstacle in checking the spread of the beetle. 

Maryland. E. N. Cory (August 22): Infestation in the sprayed area is much light! 
than last year. There is a marked difference in the condition of sprayed and 
unsp rayed foliage. 

ASIATIC GARDEN BEETLE ( Autoserica castanea Arrow) 

New York, New Jersey, and Pennsylvania. C. H. Hadley (June): This insect is more 
abundant than last year, and the grub injury has been much more extensive than 
during any previous season. The most serious plant injury occurred in the 
unemployment gardens (76 acres in all) distributed throughout Nassau County. 
There were large areas in several of these gardens where it was impossible to 
grow any vegetables until after the grub stage was pact. There has also been 
garden injury in private gardens (ornamental and vegetable) in Nassau and 
Westchester Counties. The injury was heaviest in gardens which were in sod 
last year, but there was also heavy plant destruction in gardens which had beei 
under cultivation for several years. In surveys made for the Japanese beetle 
the following distributional records for A. castane a were obtained; at the 
Boaderwood Golf Course at Rydal, Pa.; in Eairmount Park, Philadelphia, Pa.; 
at the St. Davids Golf Course near Wayne, Pa.; at the Seaview Golf Course near 
Atlantic City (Atlantic County), N.J. (August 22): On Long Island it has 
also been causing for the first time extensive injury in vegetable gardens, 
especially to bean, beet, cabbage, carrot, eggplant, kohl rabi, parsnip, pea, 
pepper, and turnip. 

Rhode Island. A. E. Stene (August 21): One specimen has been captured in a trap 
in Westerly. 

JAPANESE SERICA (Serica similis Lewis) 

New York. C. H. Hadley (June): On June 15 S. similis was taken at Mill Neck, for 
the first time. At this locality during June, 178 adults were taken in the 
traps which were set up to catch Japanese beetles. 

WIREWORMS (Elateridae) 



Vermont. H. L. Bailey (August 21): Wireworms are very abundant. They, have damage 
corn severely in various parts of the State, particularly in Windham County.

WHEAT 

HESSIAN ELY (P hytopha ga destructor Say) 

Ohio. T. H. Parks (August 24): A survey of 26 counties shows the present 

infestation to "be slightly more than 8 per cent, compared with 34 per cent 
infestation in 1932. The infestation ranges from 2.4 per cent in Drake County 
to 15.6 per cent in Clinton County. There was no serious damage to any wheat 
in 1933. 

Illinois. W. P. Flint (August): The results of the Hessian fly survey for

WHEAT MIDGE ( Contarinia t ritici Kby.) 

Ohio. T. H. Parks (August l): We have received a sample of wheat from Fairfield 
County with so many of these larvae in it that the owner feared to store the 
grain. From the numbers of the larvae present the insects must have damaged 
the milky kernels and reduced the yield. No general outbreak of the wheat 
midge occurred in Ohio. 

BLACK GRAIN STEM SAWFLY ( Trachelus tabidus Fab.) 

Virginia. J. S. Pinekney (June): Slight infestations of this sawfly were found 
in the Counties of Louisa (2 per cent), Spotsylvania (1 per cent), Essex (1 
per cent), King George (1 per cent), Piichmond (1 per cent), Westmoreland (1 
per cent), and Fairfax (1 per cent). Other counties in the principal wheat- 
growing areas showed no infestation. Injury to wheat from this source was 
obviously negligible. The survey was based on the examination of 5 widely 
distributed samples of wheat stems from each County. 

Maryland. J. S. Pinekney and S. J. Udine (July): Infestations of the black grain- 
stem sawfly were found in the Counties of Baltimore (11 per cent), Carroll (4 
per cent), Frederick (5 per cent), Earford (2 per cent), Howard (2 per cent), 
Montgomery (6 per cent), and Washington (2 per cent). Injury to the wheat 
crop from this source was negligible. Five widely distributed samples of 50 
wheat stems each from each county formed the basis of this survey. This is 
a noticeable increase in infestation over last year, when no sawflies were 
found in the course of a similar survey. 

Pennsylvania. C. C. Kill, J. S. Pinekney, and S. J. Udine (June - July): Infes- 
tations in wheat were found in all sections of the State surveyed for this 
pest. In many fields the grain was conspicuously knocked over from this 
cause, with the accompanying loss of wheat usually experienced by lodging. 
Each sample examined consisted of 50 stems. The infestations by counties 
are as follows:

prevalent in the eastern part of Oliver County. 

SAY'S STINK BUG ( Chlorochroa say_i Stal) 

Montana. ' A. L. Strand (August 19): The grain bug or Say's plant bug has been 
exceptionally abundant in grain fields of north-central Montana. This is 
believed to be the first important outbreak of this insect in the State.

Ohio. T. H. Parks (August 24): The chinch bug :'.s very abundant. 

Illinois. W. P. Flint (August 22): Weather conditions have been highly favorable 
for the development of chinch bugs throughout centrrl Illinois. In most cases 
the rainfall has been below normal and temperature conditions about normal. 
This has resulted in a heavy second brood of the bugs. At present more or 
less serious damage is occurring in about 60 counties, with prospects for a 
still greater population next year. 

Michigan. F. I. McDaniel (August 9): The chinch bug continues to appear in the 
southern two tiers of counties of Michigan.

abundant in Pepin County. 

Minnesota. A. G. B-uggles (August 21): The chinch bug is very abundant in a few 
counties. 

Iowa. C. J. Brake (August 28): Weather conditions have been favorable for both 
the first and second generations of chinch bugs in southern Iowa. The second 
generation is scattered very widely, and around 25 to 30 counties in southern 
Iowa are infested. Extensive burning campaigns have been planned for this fall. 

Missouri. L. Hasemaii (August 23): The chinch bug situation is alarming. The 

summer generation of young is very abundant on corn, even feeding in sweet corn 
ears at Columbia. 

Kansas. H. R. Bryson (August 21): Chinch bugs are not so numerous at Manhattan 
as might be expected at this time of year, if one compares the present 
abundance with that observed at harvest time. 

Oklahoma. C. E. Sanborn (August 22): Chinch bugs are abundant in some localities. 

Nebraska. M. K. Swenk (August 21): Chinch bugs are very abundant in southeastern

damage this month but is not so abundant as it has been some years. 

Tennessee. G. H. Bentley (August 15): The corn ear worm is scarce. 

Louisiana. 17. E, Hinds (August 29): The corn ear worm is very abundant in late 
corn. 
. 

Oklahoma, C. F. Stiles (August 22): Corn ear worms are causing untold damage 

throughout Oklahoma. They are attacking all late corn, cotton squares, bolls, 
kafir heads, and even the leaves on peanut plants. Tomato is also being 
seriously injured. 

Colorado. G. M. List (August 24): The corn ear worm is less abundant than usual. 
Very few of them have been reported in sweet corn but there' is' an occasional 
specimen found in tomatoes. 



-233- 

Utah. G. F. Knowlton (August 5): Damage to sweet corn is quite general in 

northern Utah. (August 18): Injury to sweet corn occurred later than usual 
in Cache Valley, and much of the corn has "been harvested with a low percentage 
of infestation. 

STALK BORER (Pap_aip_ema nebris nitela Guen.) 

New Hampshire. L. C. Glover (August 23): The stalk "borer is moderately abundant. 

Massachusetts. A. I. Bourne (August 22): The common stalk borer was present very 
generally, but apparently in considerably less than normal abundance. 

New York. P. J. Parrott (August 23): The stalk borer is moderately abundant. 

New Jersey. B. F. Driggers, R. C. Burdette, and C. C. Hamilton (August 25): The 
stalk "borer is moderately abundant. 

Delaware. D. MacCreary (August 23): The stalk "borer is moderately abundant in 
sweet corn plantings at Bridgeville.

several stock plants. 

Indiana. J. J. Davis (August 29): Stalk borer reported abundant on potato at 
Milton, July 23. 

Iowa. H. E. Jaques (August): The stalk borer is present generally throughout 
the State, being moderately abundant in most localities. 

LESSER CORN STALK BORER ( Elasmopalpus lignosellus Zell.) 

Virginia. H. G. Glover (August 25): Tae lessor corn stalk borer has been causing 
rather serious damage to young Ford Hook lima beans in some fields on the 
Eastern Shore of Virginia. 

North Carolina. W. A. Thomas (August) : The lesser corn stalk borer was extremely 
destructive on corn, cowpeas, and beans during late July, in many cases 
completely destroying the stand of plants at Chadbourn. In early August the 
larvae wcsr^doing considerable damage to young runner strawberry plants. 

South Carolina. 0. L. Cartwright (August 21): The lesser corn stalk borer did 
more injury in the State than usual, especially in the eastern portion. 

Georgia. W. H. Clarke (August 2): A large field of late corn at Fort Valley has 
been ruined. Most of the corn is dead and the remainder of no value, 
practically every stalk showing injury. 

Florida. J. R. Watson (August 24): The lesser corn stalk borer, which was so 
injurious to corn the early part of the season, also did considerable damage 
to cowpeas later on. 

SOUTHERN CORN STALK BORSR ( Diatraea crambidoides Grote) 

South Carolina. 0. L. Cartwright (August 21): There is more infestation by the 
larger corn stalk borer at Clemson College than usual. 



-234- 

CORN ROOT WEBWORM ( Crambu s caliginosellus Clem.) 

Kansas. H. R. Bryson (August 21) : Reports of injury of the sod webworm (C. 
caliginosellus Clem.) were received from Norton and Bloom on July 27 and 
August 1, respectively. 

CORN LEAF APHID ( Aphis maidi s Fitch) 

Indiana. J. J. Davis (August 29): Corn leaf aphid was reported seriously 
damaging corn at Jeffersonville, August 19. 

Michigan. R. H. Pettit (August 19): We have received large quantities of the 

corn leaf aphid from Traverse City, Sault Ste. Marie, and Fremont. It is also 
reported as "being very common in the Upper Peninsula. Wherever it occurs, it 
is in enormous numbers. 

Nebraska. M. H. Swenk (August 21): Reports from Otoe, Dodge, and Nance Counties 
stated that the corn leaf aphid was infesting corn. A York County correspond- 
ent reported it working on pep corn. 

Kansas. H. R. Bryson (August 21): The corn leaf aphid has been unusually 

destructive to late corn and sorghums in Kansas this season. In many instances 
the tassels have been so injured or infested as to interfere seriously with 
pollination. Two reports were received from Orion and Spearville. The 
infestation is heavier on sorghums at Manhattan than it has been for several 
years. 

Iowa. C. J. Drake (August 28): Heavy infestation may be found locally throughout 
Iowa. Near Sheffield approximately one-half of five hundred acres of corn 
has been destroyed. 

COLORADO CORN ROOT WORM ( Diabrotica virgifera Lee . ) 

Nebraska. M. H. Swenk (August 21): An inquiry concerning the Colorado corn root 
worm was received from Redwillow County on August 15. 

CARROT BEETLE ( Ligyrus gibbosus DeG.) 

South Carolina. 0. L. Cartwright (August 21): Carrot beetles are now being taken 
in trap lights at Clemson College in large numbers. 

Indiana. J. J. Davis (August 29): Adults were eating the underground parts and 
killing sunflowers planted for the seed crop at Kendallville, August 10. 

SOUTHERN CORN LEAF BEETLE ( Myochrous denticollis Lee . )

Countjf, on August 18, the sender indicating that he found a number of them on 
corn plants. 

CORN BILLBUGS ( Calendra spp.) 

South Carolina. 0. L. Cartwright (August 21): Billbugs are doing more damage to 
corn than usual at Florence. 



-235- 

A BUMBLE FLOWER BEETLE ( Euphoria inda L.) 

Michigan. R. H. Pettit (August 23): E. inda has just appeared in ears of sweet 
corn. During the past week samples have "been sent in from Marine City and 
Vestaburg. 

Minnesota. A. G. Ruggles (August 21): Many reports have "been received of 
abundance of this "beetle on sweet corn. 

ALEALEA 

ALFALEA WEEVIL ( Hyp era postica Gyll.) 

Nevada. G. G. Schweis (August 21): Alfalfa weevils are very numerous in the 

fields, much more so than in the past several years. If something unforseen 
does not happen to them during the winter, the prospects are for a lot of 
damage next spring. 

Iowa. R. W. Haegele (July 27): The alfalfa weevil is moderately abundant in 
eastern Idaho. 

California. A. E. Michelbacher (August 2l): The alfalfa weevil in most areas 

is hard to find. In the territory about Tracy and Pleasanton "both the larvae 
and adults are very scarce. In some fields in the Niles area both adults and 
larvae can be taken in small numbers. In one field one half grown (fourth 
crop) an average of 45 larvae and 2 adults were taken per 100 sweeps. 

SOUTHWESTERN ARMYWORM ( Prodenia praefica Grote) 

California. A. E. Michelbacher (August 21): The yellow striped armyworm caused 
some damage to the fourth crop of alfalfa in the region about Vernalis (near 
Tracy) . On August 7 the damage was severe enough in spots in several fields 
to give the alfalfa a grayish tinge. 

ALFALFA CATERPILLAR ( Eurymus eury theme Bdv.) 

Arizona. C. D. Lebert (August 26): Adults have been exceptionally numerous in 
the alfalfa fields of the Salt River Valley during the month of August. 

California. A. E. Michelbacher (August 21): On August 7 the alfalfa butterfly 
was observed to be rather abundant in the territory about Pleasanton. On 
August 21 many of the butterflies were observed flying in the fields about 
Tracy. 

A CHRYSOi-IELID ( Zygogremma conjunct a Rogers) 

Nevada. G. G. Schweis (August ll): Specimens were collected on alfalfa and 
weeds in Nye County. 

COWPSAS 

COWPEA CURCULIO ( Chalcodermus aeneus Boh:i) 

North Carolina. I?. A. Thomas (July 15): The cowpea pod weevil is present in the 
fields at Chadbourn in about the same numbers as last season. It has been 



-236- 

observed that certain varieties of cowpeas are much more susceptible to 
attack than others, notably the Crowder variety. 

CROTALARIA 

BELLA MOTH (Utet heisa bella L.) 

South Carolina. 0. L. Cartwright (August 21): Bella moth larvae are doing 
noticeable damage to seedpods of Crotalsria at Florence. 

SOYBEANS 

VELVST3EAN CATERPILLAR ( Anticarsia ^emmatilis Hbn.) 

Louisiana. W. E. Hinds (August 39): A. gemmatilis is stripping soybeans in a 
few areas in southern Louisiana and mots (probably migrated specimens) are 
being found at Baton Rouge and at o£her points farther North. We find that 
the eggs of this species are being attacked by Trie ho gramma , as we would 
expect them to be. The highest parasitism found thus far isiamong Anticarsia 
eggs laid on soybeans planted in a cornfield where we liberated Trichogramma 
for the control of Diatraea saccharal is Fab. The colonization was made on 
August 5, and on August 24 95 per cent of the Anticarsia eggs were found 
parasitized. 

SUGARCANE 

SUGARCANE BORER ( Diatraea sac charalis Eab . ) 

Louisiana. W. E. Hinds (August 29): Sugarcane borers are increasing quite 

rapidly with the beginning of the fourth generation now underway. Heaviest 
infestation is restricted to comparatively small areas and is not general. 
Trichogramma minutum Riley parasitism in borer eggs is running somewhat below 
the general average for this date a year ago but colonization is showing a 
distinct advantage as in previous years. 



FRUIT INSECTS 

APPLE 

CODLING MOTH ( Carpocapsa -pomonella L.) 

South Carolina. W. C. Neetles (August 21): Very severe damage is being caused 
at Clemson College by the third brood; previous damage was light. 

Ohio. T. H. Parks (August 24): The codling moth is more troublesome than usual. 
The season has been very favorable to the insect, and a few orchards which 
have suffered damage in the past have more worm entrances than in former years. ^ 
This is apparently due to the use of calcium arsenate in the second-bro.od 
spray. Some orchardists who followed a very complete and careful spray 
program are experiencing serious trouble with late entering worms. The out- 
break is largely limited to Lawrence County and to orchards along the west 
end of Lake Erie. 



J 



-237- 

Indiana. J. J. Davis (August 29): Codling moth has had unusually favorable 
conditions the past season and has '"been most difficult to holc^ in check. 
Huge losses have resulted. 

Illinois. W. ?. Flint (August 22): The codling moth is still extremely abundant. 
Large numbers of moths are now being taken in bait traps, both in southern and 
central Illinois. The hatch of worms will certainly continue up to and 
probably beyond September 1. 

Wisconsin. C. L. Fluke (July 25): The codling moth is moderately abundant. The 
second brood began emerging the middle of July. 

Missouri. L. Baseman (August 23): A very heavy moth emergence has been on since 
August 15. Late worms are a real problem throughout State. Control is quite 
satisfactory, however. 

Kansas. H. R. Bryson (August 21): An examination of banded apple trees at the 
College Horticultural Farm at Manhattan August 19 revealed as many as 150 
larvae per tree. The infestation at this farm is very much greater than last 
year. 

Nevada. S. G. Schweis (August 21): The codling moth is very abundant at Reno. 
Practically all un sprayed fruit is infested. 

Utah. G-. F. Knowlton (August 18) : Codling moths have attacked most of the 

apples at The Dell, in Skull Valley. Two sprays were applied. The insect 
is moderately abundant in northern Utah and doing considerable damage on a 
light crop of apples. 

EASTERN TENT CATERPILLAR ( Mai aco soma americana Fab.) 

Connecticut. W. E. Britton (August 24): The eastern tent caterpillar is very 
abundant. 

North Dakota. J. A. Munro (August 25): Reports that the tent caterpillar is very 
abundant in Valley City and vicinity have been received. 

FRUIT TREE LEAF ROLLER .( Cacoe cia argyrospila Walk.) 

New Mexico. J. R. Eyer (July 24): Fruit tree leaf rollers are moderately abundant 
all over the State. 

APPLE LEAF SKELETONIZES (Psorosina hammondi Riley) 

Kentucky. M. L. Didlake (August 25): The apple leaf skeletonizer is very abundant 
in western Kentucky. 

Tennessee. G. M. Bentley (August): Apple leaf skeletonizers were collected 
July 22 in Obion County, 16 miles from Union City. Adults were obtained 
August 7 from the material . 

APPLE MAGGOT ( Rhagoletis porno nella Walsh) 

New Hampshire. L. C. Glover (August 23): The peak in emergence of adults from 10 
cages placed under trees in the. University orchard occurred between July 24 



-238- 

and 26. A lesser peak occurred on July 20, Two peaks of emergence of adults 
from second-year puparia were noted; one on July 8 and one .on July 12. 

WOOLLY APPLE APHID (Sriosoma lanigerum Hausm.) 

California. E. 0. Essig (August 21): The woolly apple aphid is very abundant at 
Berkeley. 

SAN JOSE SCALE ( Aspidiotus perniciosus Comst.) 

Tennessee. G. M. Bentley (August): The San Jose scale is moderately abundant 
all over the State, in orchards and on wild stock. Nursery stock is fairly 
clean. 

PEAR LEAP BLISTER MITE ( Eriophyes pyri Pgst.) 

Utah. 0. F. Knowlton (August l): Pear leaf blister mites have caused serious 
injury to a few apple trees at Smithfield. Apple trees at The Dell are 
heavily infested. 

PEACH 

ORIENTAL FRUIT MOTH ( G-rapholitha molesta Busck) 

Massachusetts. A. I. Bourne (August 2§): Injury by the oriental fruit moth is 
very general in peach-growing sections. 

Connecticut. P. Carman (August 23): In general the infestation is declining, 
but there are prospects of considerable damage in some orchards this year. 



Delaware. D. MacCreary (August 23): The oriental fruit moth is moderately 
abundant on peaches. Fruit injury is somewhat greater in some areas than 
during the previous three years. 

■ 

Maryland. H. S. McConnell (August 22): The oriental fruit moth is very abundant. 



1 



Illinois. W. F. Flint (August 22): Oriental fruit moth adults have been taken in 
larger numbers than usual in bait traps. 

South Carolina. W. C. Neetles (August 21): At Clemson College thare was less 
damage than usual to Elberta peaches, but more damage tnan usual to varieties 
ripening later than Elberta. 

Ohio. E. W. Mendenhall (August 24): The oriental fruit moth is very abundant 
this year all over the State, especially where treatment was not given. 

Indiana. J. J. Davis (August 29): The oriental fruit worm has been very abundant 
The earliest peaches were not heavily infested in many cases but the later 
peaches were almost universally infested and frequently very heavily infested. 
Where peaches adjoin or are interplanted with apple, the apple fruit will 
almost certainly show a high infestation. 

Arkansas. D. Isely (August 23): The oriental fruit moth is unusually abundant 
for this time of year in green peach shoots. Probably this is due to the late 
rains which have- caused an. excessive amount of green growth. ' 



-239- 

Georgia. 1. H. Clarke (August 4): At Woolsey and Thomas ton twigs have hardened 
and larvae are scarce in twigs. (August ll): At Newman the larvae are scarce 
in twigs; at Madras a good many larvae are found in twigs, and succulent 
growth is plentiful and has not hardened in this orchard. 

0. I. Snapp (August l): As usual, the fruit infestation was extremely light 
this year at Fort Valley. Of 6,480 peaches cut open and examined, only 24, 
or 0.37 per cent, were found to be infested. Of 12,217 Elberta peaches cut 
open and examined, only 17, or 0.14 per cent, were found to be infested. A 
total of 18,697 peaches were cut open and examined in the Hiley and Elberta 
orchards, and the average percentage of them infested was only 0.22. 

Tennessee. G. M. Eentley (August): The oriental fruit moth is scarce all over 
the State. Apparently this is the time between broods. Early damage was 
heavy. 

PEACH BORER ( Aegeria exitiosa Say) 

New York. P. J. Parrott (August 23): The peach borer is very abundant. 

Georgia. 0. I. Snapp (August 21): Field mice and rats are again destroying many 
pupae at Port Valley. We are finding hundreds of empty fresh cocoons near 
the base of peach trees which these predators dug out of the ground or tree 
and then ate out the contents. In all probability the infestation will be 
reduced again by the activity of these predators. 

Tennessee. G. M. Eentley (August): The peach borer is very abundant in Knox 
County; plentiful in old orchards and scattered seedlings. 

PLUM CURCULIO ( Conotrachelus nenupha r Kbst.) 

South Carolina. 'If.., CL, Neetles (August 21): The plum curculio is doing less 
damage to peaches this season than usual. 

Georgia. 0. I. Snapp (August 21): The entire peach crop at Fort Valley was 
harvested with an infestation less than that of an average year. This was 
due to delayed emergence of first-generation adults from the soil in peach 
orchards as a result of dry weather in May and June. A few second-generation 
eggs were deposited as long as there were peaches in the orchards, but the 
majority of the new beetles will go into hibernation without having deposited 
any eg;'s this year. Therefore, oviposition in 1934 is expected to be heavier 
than it would have been had the first-generation adults deposited a part of 
their eggs in 1933. 

Ohio. S. w. Mendenhall (August 24): The plum curculio is very abundant on plum. 

Wisconsin. C. L. Fluke (July 25): The plum curculio is very abundant; there is 
a very heavy infestation in Richland County. 

Arkansas. P. D. Sanders (August): Three curculio emergence cages, located in 
Howard, Pike, and Hempstead Counties in southern Arkansas, showed that the 
peak of first-brood adults emerged from the soil between June 12 and 20. Since 
the bulk of the commercial peach crop was not harvested until late in July, 
a second brood occurred. The extremely dry we at he j/ prevailed while the 
insects were in the soil and a thorough-going control program were apparently 
responsible for the slight damage this year.

CHERRY 






CHEEKY FRUIT FL.Y ( Rhagoletis c ingulata Loew) 

Oregon. S. C. Jones (July 25): The cherry fruit fly "began emerging June. 16; the 
peak was reached July 11. First maggots were found in Royal Ann cherries on 
July 6, at Macleay, in un sprayed plots. First full-grown maggots were found 
in a commercial orchard at Springfield on July 12 in Waterhouse cherries. First 
pupae were formed July 20 at Macleay. (August 25): The cherry fruit fly^was « 
still emerging from ground August 24 at Rickreall. Cherries still on trees 
heavily infesded with maggots. 

A SCALLOP SHELL MOTH (CalocaLpe undulata L.) 

Massachusetts. A. I. Bourne (August 22): The last week in July there was dis- 
covered a considerable area in Plymouth County, particularly in the vicinity 
of Middleboro, where wild cherries were well-nigh defoliated ~Dy the cherry 
scallop shell moth. In many cases the trees had practically no green foliage 
left and were entirely covered by the peculiarly rolled and webbed leaves. 
In many cases these injured leaves had fallen and the trees were nearly as 
bare as during the dormant season. 

SHOT-HOLE BORER ( Scolytus rugulosus Ratz.) 

Indiana. J. J. Davis (August 29): Shot- hole borer was destructive to plum and 
cherry at West Baden and Cicero according to reports received the middle of 
the month. 

ANTS (Formicidae) 

Utah. G. F. Knowlton (August 24) : Ants appear to have been responsible for 
killing a number of young cherry trees at Sandy, having made their nests 
around the bases of the trees. They are on the leaves in large numbers, 
attending the black cherry aphids which have severely curled most of the leaves 
on the trees still alive. 

PLUM 

PLUM GOUG-SE ( Anthonomus scutellaris Lee.) 

Minnesota. A. G. Ruggles (August 21): The plum gouger, heretofore only rarely 
seen, has been sent in a number of times from St. Paul, Mankato, and other

Antelope Counties. This pest was reported also working on woodbine vines in 
Redwillow County. 

Utah. G-. P. Knowlton (August l): Leafhoppers E. comes ziczac Walsh are causing 
serious injury to Virginia creepers in all sections of Logan, and damage has 
been noted in many parts of northern Utah. (August 5): A species of 
B rythronoura is seriously damaging Virginia creeper and Engleman's ivy at 
Riverheights, Hyrum, Logan, Millville, and Salt Lake City. Many of the 
leaves have already dried up and fallen, owing to the leafhopper attack. 
(August 9): Grape leafhoppers are seriously damaging grapes at Roy. Most 
of the older leaves are badly spotted and yellowed. Some leaves are falling 
off. (August 18): Grape leafhopper damage continues to become more severe 
in many parts of northern Utah, particularly on Virginia creeper. In Logan 
from 10 to 75 per cent of the leaves of nearly all Virginia creepers are now 
brown and falling off. Damage to grapes is less severe, but increasing in 
several localities, including Brigham, Ogden, and Salt Lake City. 

GRAPE LEAF FOLDER (Desmia funeral is Eon.) 

Missouri. L. Haseman (August 23): The grape leaf folder has done quite a little 
damage during the month at Columbia. 

GRAPE BERRY MOTE ( Polychrosis viteana Clem.) 

Michigan. R. H. Pettit (August 23): There is a serious attack by the grape berry 
moth. Enormous numbers of eg; - s have been laid and are no?; beginning to hatch. 
We are just beginning to pick Moore's Early grapes; in fact, many growers in 
Berrien County began picking yesterday and are now looking forward to enormous 
numbers of the moth on the Concord and other later varieties. 

PS&Q 

PECAN WEEVIL ( Curculio caryae Horn) 

Georgia. T. L. Bissell (August 14): Adults of the pecan weevil were found in 
considerable numbers at Strouds Crossroads on July 22, 2 weeks earlier than 
in 1932. At Experiment, activity began about 1 week earlier than in 1932. 

AN APHID ( Monelli a costali3 Fitch) 

Georgia. T. L. Bissell (August 14): The black-margined aphid is more abundant 
on pecan for this time of year than in several years, at Milner and Strouds 
Crossroads. Pecan trees have excessive quantities of honeydew. In one place 
honeydew was conspicuous on a dirt road which was overhung by pecan limbs. 
In the Experiment section the species is usually most abundant in May and 
again in September or October.

sections recently, specimens collected in pecan orchards having been received 
from Jones, Perry, and Pike Counties. 

CITRUS 

CITRUS WHITSFLY ( Dialeurodes citri Riley and How.) 

Florida. J. R. Watson (August 24): The citrus whitefly is unusually abundant 
this year. Abnormally low rainfall for August in some sections has delayed 
the multiplication of the entomogenous fungi, 

E. IT. Berger and G. B. Morrill (August 23): This species and D. citrifolii 
Morg. are moderately to very abundant in various localities. Some citrus 
plantings are almost free of whiteflies, thanks to effective growths of fungi 
in such plantings during 1932. 

Mississippi. G. L. Bond (August 19): The citrus whitefly is very abundant a.round 
shrubbery at Lexington, Durant, and Greenwood. 

H. Gladney (August 16): The citrus whitefly is very abundant on citrus at 
Ocean Springs. 



LOSG- TAILED MEALYBUG ( Pseudococcus a donidum L.) 

California. H. J. Ryan (August 22): The long-tailed mealybug P. lonispinus , was 
found severely infesting a few citrus orchards near Whittier. Occasionally 
severe infestations in greenhouses and on ornamentals have been kne-.m in 
southern California for 15 years or more, but this mealybug has never before 
been found in great numbers on citrus. Associated in the Rivera section with 
Baker's mealybug, P. mar i t imus Ehrh. , and the citrophilus mealybug, P. gahani 
Green, both of which are thoroughly under control this season by predators 
and parasites, the infestation by the long-tailed mealybug has so far been 
found only in some 10 or 12 groves where spraying, instead of fumigation, 
was applied last season for scale control.

harvest was not over 25 per cent of a normal crop, the yellows being the 
principal cause for this reduction. In the San Luis Valley and in other high 
mountain producing areas the infestation is quite heavy on late potatoes, but 
the loss will not be so great as it was a year ago. In Weld and Morgan Counties, 
where the crop was reduced almost 75 per cent last year, the yield will be

General. :T. F. Howard (August 29); Throughout Kentucky, Tennessee, Virginia, 

West Virginia and the eastern portion of the Carolinas the Mexican bean beetle 
has been less destructive than a year ago. While early beans were injured to

on August 7 from Wallerville, Union Coxuity, and Hickory Flat, Benton County. 

Colorado. G. M. List (August 24): The Mexican bean beetle appeared later than 
usual from hibernation and many producers Trot the idea that the injury would 
not be great. As a result the control was not as general as usual and the 
loss is proving to be quite heavy in many sections. 

New Mexico. J. R. E r er (July 24): The Mexican bean beetle is very abundant in 
all bean-growing districts.

INSECT PEST SURVEY BULLETIN 



Vol. 13 October 1, 1933 No. 8 

TIE MOBS IMPORTANT RECORDS EOR SEPTEMBER, 1933 

By the middle of September adults of the Japanese "beetle had dwindled 
to insignificant numbers. There was a general reduction of beetle populations 
in the older infested area over those of 1932. 

During the latter part. of September the pink, boll worm was found in the 
vicinity of Enigma, G-a. This is the first time this insect has appeared in 
Georgia. 

During September weather conditions over much of the chinch-bug belt 
were favorable for this insect. , By the middle of the month about three 
fourths of the bugs had reached the winded stage and heavy flights were oc- 
curring. Unless weather conditions are unfavorable for this insect next 
soring a serious outbreak will occur in the eastern part of the belt. 

Erom surveys made by State workers the European corn borer has been found 
in 15 additional townships and 7 -additional counties in Wisconsin this year. 
Last year it was found to be infesting 3 fields in 3 counties. 

A European weevil, Sitona cylindricollis Pab . , which is a minor pest of 
alfalfa and sweet clover in Europe, has been recorded for the first time in 
this country from Middlebury, Vt., where it was causing injury to seedling 
plants of sweet clover this spring and has continued to feed on the foliage 
throughout the summer. The insect is also reported from Connecticut, New 
York, and Massachusetts by R. Copple of the Bureau of Plant Industry. 

The velvetbean caterpillar has been defoliating soybeans in a few local- 
ities in Louisiana and badly ragging velvetbeans in parts of Florida. 

The codling moth is more abundant throughout the New England, Middle 
Atlantic, East Central, and West Central States than in 1932. Considerable 
late injury occurred throughout most of this region and there are prospects 
of a heavy carry-over of larvae . 

The bumble flower beetle has increased to rather unusual numbers in the 
Northeastern States from Vermont to Minnesota and southward to Virginia. 

The caterpillar Homalopalpia dalera Dyar has been quite generally injurious 
to papayas during the month, as was also the papaya fruit fly in Florida. 

A serious outbreak of the screw-worm fly in Florida and Georgia developed 

. -265- 



-266- 

during the month. This is the first serious infestation of this insect in the 
southeastern part of the United States. 

An outbreak of the serious disease of horses known as encephalonyelitis 
continued in Maryland, Delaware and Virginia; : The fact that this disease has 
been transmitted experimentally by mosquitoes has directed much attention to 
the mosquito question. There has emerged from the salt marshes of the Central 
Atlantic States a series of heavy broods of salt marsh mosquitoes, which have 
given abundant opportunity for the spread of the disease if these species are 
concerned. 

THE MORE IMPORTANT ENTOMOLOGICAL FEATURES IN CANADA FOR THE 
PERIOD, JULY - SEPTEMBER, 1933. - 

The serious outbreak of grasshoppers in the three prairie Provinces of 
Manitoba, Saskatchewan, and Alberta caused great damage to wheat and other 
crops over a very wide territory. Increase in numbers and migrations involved 
much territory that previously was only lightly infested. In some districts 
the situation was so threatening as to cause many farmers to cut their crops 
on the green side to minimize losses. After the grains had been harvested 
the grasshoppers turned more to weeds, grasses,- garden truck, and other late 
crops, and their ravages were still continuing early in September. Reports 
indicate that very large areas will be even more heavily infested in 1934. 
In British Columbia, where grasshoppers have "been at a low ebb in recent years, 
there are evidences of a general increase that may presage a further outbreak 
in this province. In eastern Canada grasshopper infestations continued moder- 
ate in most localities. 

A more extensive outbreak of the pale western cutworm is expected in 1934, 
in Alberta and Saskatchewan, than occurred this spring. 

Very heavy infestations of the wheat stem sawfly and an unusually high 
degree of loss of wheat infested by this species were observed in a number of 
districts in Saskatchewan. Sawfly damage was also evident in south-central 
Alberta. 

The wheat stem maggot again caused some injury to wheat in Manitoba, the 
damage ranging from less than 1 percent in some areas, to nearly 15 percent in 
others. Practically all parts of the province were affected. 

Heavy infestations of second-year white grubs occur over an area of at 
least 5,000 square miles in eastern Ontario. Timothy meadows and crops such 
as strawberries and corn have been seriously damaged. In southern Quebec, the 
adult beetles are more numerous in the soil than in 1930, and hence a large 
flight is anticipated over much of agricultural 'Quebec in 1934. No injury to 
the roots of common farm crops will occur until July of that year. 

The Colorado potato beetle was widespread over settled areas of the , 
Prairie Provinces, notably in Manitoba and southern Alberta, where it was more 
destructive than average. 

The beet webworm was conspicuously abundant in Saskatchewan, particularly 
in the northern settled portion of the Province. It attacks vegetable and 



-267- 

flower-garden plants, native fruit trees, and weeds, and is of some economic 
importance. It was also general in Manitoba and some areas of Alberta. 

In AlDerta, Saskatchewan, and the Okanagan Valley, British Columbia, 
"butterflies of the imported cabbage worm were reported exceptionally numerous, 
and larval infestation on curciferous crops was general. They were also 
locally reported remarkably abundant in eastern Ontario. 

Blister beetles of several species were abundant and widely distributed in 
sections of the Prairie Provinces. Caragana and various garden crops were 
attacked. 

Insect pests of fruit were generally well under control in the fruit-grow- 
ing sections of the Dominion. 

Hot, dry conditions of southern Ontario favoured codling moth development 
and resulted in an unusually large amount of side-worm injury. The gray-banded 
leaf roller took some toll in the Annapolis Valley, Nova Scotia. 

Local outbreaks of the apple aphid occurred in southern Ontario, and in 
parts of the Saint John River Valley, New Brunswick. This species and the 
cherry aphid were troublesome in the Okanagan Valley, British Columbia. 

Fruit-injury records taken in the Niagara district, Ontario, indicated 
that the oriental fruit moth infestation was similar to that of 1932. The 
fruit moth infestation was reduced to some extent by hot, dry weather in June 
and July. 

An increase in the numbers of the European spruce sawfly, Drprion 
polytomum Hartig. , occurred this year on spruce in the Gaspe Peninsula, Quebec. 
This species first rose to prominence as a pest in this area in 1931. The heavy 
attack has extended along the north shore of the St. Lawrence, and along the 
Matapedia Valley. A severe infestation of the yellow-headed spruce sawfly on 
plantations and ornamental groups of white spruce developed over a wide area 
in Saskatchewan. 

Outbreaks of the eastern spruce beetle on Cape Breton Island, injurious 
to white and red spruce during the past five years, appear to have died out. 
This species is also distinctly less abundant in the Gaspe Peninsula where it 
has caused heavy damage in recent years. 

There was _a general and fairly heavy attack of the birch skeletonizer in 
the Maritime Provinces and the Gaspe Peninsula, but the species was less numer- 
ous than in 1932. 

The satin moth infestation in New Brunswick has spread and increased in the 
districts of Sussex, Moncton, Sackville, and Amherst. It was first found in 
this Province in 1930. 

The majority of walnut trees in southwestern Ontario were partially or 
wholly defoliated by the walnut caterpillar. 

An outbreak of the spruce budworm active in the Barkerville district, 
British Columbia, during the past ten yeans, has subsided because of adverse 
weather conditions and the elimination of much of the food supply by the western 
balsam bark beetle.

GENERAL FIB'D'ElS 

GRASSHOPPERS (Acrididae) 

Florida. J. R. Watson (September 21): Grasshoppers are very abundant. Several 
species are ragging young citrus foliage rather severely. 

Tennessee. G. M. Bentley (September 23): S chistocerc a americana Drury was report- 
ed as numerous in western Tennessee although no damage seems to have been done. 
Slight damage has been reported from middle Tennessee. 

Alabama. J. M. Robinson (September 20): Grasshoppers are very abundant at Auburn. 

Kansas. H. R. Bryson (September 23): Slightly less than normally abundant, but 
not scarce. No reports of injury have been received during the latter part of 
the summe r . 

Arizona. C. D. Lebert (September 18): The only insect pest of any great concern 
at the present time is Melanopl us mexicanus Sauss. These hoppers are still 
fairly abundant in spite of the fact that drastic control measures have been 
applied to approximately 80,000 acres in the Salt River Valley. 

Nevada. G. G. Schweis (September 19): Grasshoppers have continued to do consider- 
able damage in widely separated portions of the State. 

WHITE GRUBS ( Phyllo-pharra spp.) 

Illinois. W. P. Flint (September 19): White-grub damage has been reported by the ] 
State Crop Reporters in 19 of the northeastern counties of the State. Injury 
in some sections is very severe.' 

Wisconsin. C. L. Fluke (September 23): White grubs are very abundant, principally, 
in southwestern Wisconsin. Almost the entire southern half of the State has 
sustained injury by Brood A. Injury has been most severe in pasture lands, 
corn, strawberries, and young pine trees. 

Minnesota. A. A. Granovsky (September 20): White grubs this year caused enormous 
damage to corn, strawberry, potatoes,' flax, raspberries, soybeans, sudan grass, 
and pastures. As it was expected the southeastern corner of the State suffered 
the mo s t . 
A. G. Ruggles (September 21): White grubs are very abundant. 

Iowa. C. J. Drake (September 27): Injury is very widespread in the northern part 
of Iowa, particularly in the vicinity of Iowa Falls., Waterloo, Cedar Rapids, 
Mason City, Charles City, and Hampton. At Lake Okboji, Waukon, Hampton, and 
Clarion the grubs did serious damage to the fairways in the golf courses. 
Several thousand acres of Toermanent bluegrass pasture and small grain fields 
have been badly injured or totally destroyed. The infestation is much more 
widespread and serious than it has been heretofore in the State. 

Nebraska. M. H. Swenk (August 20 to September 21): A lawn in Lancaster County 
was reported infested with white grubs and sod webworms (Crambidae). White 
grubs were reported working in a strawberry bed in Nuckolls County on September 
12. 



-269- 

Kansas. H. R. Bryson (September 23): White grubs are moderately abundant. Diggings 
made in lawns, gardens, strawberry beds, and cultivated areas in the vicinity 
of Manhattan revealed the presence of a moderate infestation. Observations 
made in one strawberry bed showed 25 grubs to the square foot. 

JAPANESE BEETLE ( Pop ill i a .japonic a Newm.) 

United States. C. H. Hadiey (September 25): The 1933 adult brood decreased 
rapidly in August, so that by the middle of September it persisted in only 
insignificant numbers. The new brood of larvae is now represented by all stages, 
but the third stage is dominant, though younger larvae are more numerous than 
at this time a year ago. In all sections of the beetle's range which had been 
reported as heavily infested previous to 1932, there appears to have been a 
general reduction of the larval population below the level reached at this time 
in 1932. Indications have been found that the area of heaviest infestation, 
which during the past several years has been most strikingly developed in the 
general vicinity of Elmer and Woodstown, New Jersey, has shifted its centre 
southward a distance of about 10 miles and is now most marked in the region 
adjoining Bridgeton and Shiloh. Scouting during the summer showed that the 
region in which Japanese beetles are of practically universal occurrence 
increased to ah out 8,600 square miles, distributed in the States of New Jersey, 
Pennsylvania, Delaware, Maryland and New York (Steten Island). This represents 
an increase of about 1,000 square miles within the year. Places coinciding 
approximately with the present limits of the area of continuous infestation are, 
in New Jersey, Neward, Morristown, and Chester; in Pennsylvania, Easton, 
Bethlehem, Reading, and Christiana; in Maryland, Elkton, and Chesapeake City; 
and in Delaware, Middletown, Smyrna and the shore of Delaware Bay as far south 
'•as the latitude of Dover. 

Connecticut. J. P. Johnson (September): The Japanese beetle is building up in 

population in all areas where previously found. It can be considered moderate- 
ly abundant in Bridgeport, where feeding can be observed more readily than in 
the year past. It has been found for the first time in Middletown, Manchester, 
and Putnam, being rather numerous in Putnam. 

Delaware. News Letter, Bureau of Plant quarantine, U.S.D.A., No. 33 (September l): 
Early in the month a report was received from Reedy Point, near Delaware City, 
Del., on the Delaware River opposite Salem County, N. J., to the efiect that ^ 
millions of beetles were being washed ashore along the beach. An investigation 
disclosed that quantities of beetles were being washed in with the tide all 
along the nearby beach. Quite an infestation of beetles was observed feeding 
on nearby foliage. Later, complaints were received at the Dover office of 
beetles being washed in at Woodland Beach in lower Delaware. The majority of 
the beetles were dead when washed ashore, but a goodly number of the survivors 
recovered and began feeding. Six traps placed at the Reedy Point bridge 
caught 3-l/2 quarts of beetles in two weeks, and 18 traps" set up at Woodland 
Beach collected 7-l/2 quarts. Beetles in considerable quantities have been 
washed ashore along Delaware Bay from Delaware City south to Kitts Hammock, 
a stretch of about 40 miles. 

BUMBLE FLOWER BEETLE (Euphoria inda L.) 

Vermont. H. L. Bailey (September 20); Considerable injury to ripening peaches 
reported in vicinity of Brattleboro. 



-270- 

Connecticut. W. E. Britton (September 22): E. inda reported attacking boxwood 
at Darien, Hartford, and Putnam. More abundant as compared with the^ average 

year. . , 

Virginia. C. R. Willey (September 22): Bumble flfeetles, E. inda ; and E. 

me lane ho lie a Horn, were" received from Charlottesville; they were collected 
feeding on "sap flowing .from borer wound in oak tree". 

A SCARABAEID ( Pachystethus lucicola Fab.) 

Massachusetts. E. P. Pelt (September 25): Coleopterous larvae, presumably those of 
the light-loving grape beetle, are reported as injuring lawns severely at 
Dal ton. 

CUTWORMS (Noctuidae) 

Virginia. C. R. Willey (September 22): A farmer near' Richmond reported cutworms 
damaging a 10-acre field of late potatoes, cutting off vines at ground, Sept. 

15. 

MONARCH BUTTERFLY ( Danaus menippe Pab.) 

Maryland. E. IT. Cory (September 25): Apparently gathering on Sept. 17 for migratioi 
as about 300 were seen on that day at Maryland University, mostly moving slowly 
southward. During the ensuing week there was similar condition, though not so 
many butterflies, in Anne Arundel County and lower Prince Georges County. On 
Sept. 23 on a trip westward an average of about 1 butterfly for every 100 yards 
was noticed along or crossing U. S. highway 40. 

District of Columbia. P. D. Sanders (October l): The monarch butterfly was observed 
flying in large numbers in Potomac Park today. 

A CRICKET ( Nemobjus carol inus Scudd.) 

North Dakota. J. A. Munro (August 21): These crickets were very abundant at 

Pargo August 9. (N. carol inus Scudd, det. by A. N. Caudell. ******This species 
has never been reported from North Dakota and in this case may have flown in 
from the South.) 

/ 

CEREAL AND FORAGE-CROP INSECTS 

CORN 

CHINCH BUG ( Blissus leucopterus Say) 

Massachusetts. E. P. tk\t (September 25): Chinch bugs are reported as abundant 
and injurious to a lawn at Dal ton. 

Indiana. J. J. Davis (September 25): We continue to receive reports of abundance 
and there is every evidence that the pest will be unusually abundant over the 
northern half of the State next year. 

Illinois. W. P. Flint (September 19): Conditions have become somewhat worse during 
the last month. The weather has been highly favorable to the bugs. At this 



-271- 

writing at least 75 per cent of the bugs have reached the mature winged stage. 
A heavy flight occurred today in the east central part of the State. Great 
numbers of "bugs were seen in the air. A few have already gone into winter 
quarters. Unless weather conditions "become such that the spring "brood is 
seriously affected, we would anticipate more damage in Illinois next year 
than at any time during the past 50 years. There is not a cornfield in any 
part of the corn belt of this State that does not show a moderate to heavy 
infestation. 

Michigan. R. Hutson (September 19): Chinch bugs are scarce. 

Minnesota. A. G. Rugbies (September 21): Chinch bugs are moderately abundant. 
Spotted infestations. 

Iowa. C. J. Drake (September 27): The second generation has greatly increased 

the population in Iowa. The infestation at the present time includes practical- 
ly all of the southern half of the State, being heaviest in the two southern 
tiers of counties. 

Nebraska.. M. H. Swenk (September 21): The chinch bug is very abundant, especially 
in the southeastern and south-central counties. 

Kansas. H. R. Bryson (September 23): Chinch bugs are scarce. They were found 
clustered on young feterita plants in August at Manhattan. They are not 'to ■ 
be found in numbers at the present writing. One report from Kansas City on 
September 16 stated they were injuring corn. 

CORN EAR WORM ( Helioth is obsoleta Fab . ) 

New Hampshire. L. C. Glover (September 25): We have not had nearly so many 
complaints this year as last. 

Pennsylvania. T. L. Guyton (September 25): The corn ear worm is fairly abundant 
in late corn in the vicinity of Harrisburg. This insect was not so abundant 
in the earlier corn. 

Maryland. E. II. Cory (September 25): The corn ear worm is very abundant. 

West Virginia. L. M. Peairs (September 21): The corn ear worm is very abundant in 
northern West Virginia. 

Virginia. C. R. Willey (September 22): The corn ear worm was reported as being 
very damaging to several fields of late corn, Sept. 18, in Goochland County. 
Apparently this corn is very late. The worms are working in the bud, and 
there seems to be practically 100 per cent infestation. 

South Carolina. P. Sherman (September 19): The corn ear worm is more destructive 

to corn than usual, riddling tops as well as eating into tips of ears. Larvae 

have also been sent with report of injury to peas and beans, presumably of late 
planting. 

Florida. J. R. Watson (September 21): The corn ear worm is very abundant, feeding 
mostly on beggarweed seed. 



-27.2- 

Illinois. J. H. Bigger (September): The corn ear worm is moderately abundant in 
western Illinois, 30.7 per cent ears infested. 

Indiana. J. J. Davis (September 22)*' The corn ear worm is very abundant through- 
out the State. 

Michigan. R. Hutson (September 19)': Tae corn ear worm is moderately abundant. 

Minnesota. A. G-. Bungles (September 21): The corn ear worm is Very abundant. 

Alabama. J. M. Robinson (September 8): The corn ear worm is very abundant at 

Auburn, Chestnut, and Pairhope. At Pairhope corn was destroyed before tassel- 
ing. (September 20): The corn ear 'worm is moderately abundant at 'Chestnut 
and Auburn. 

Kansas. H. R. Bryson (September 23): The corn ear worm is moderately abundant at 
Manhattan; moths are quite numerous on flowers. Truck growers report the larva 
destructive to late sweet corn. 

Nevada. G. G. Schweis (September 19): The corn ear worm has been reported as 

doing less damage this year than in the past several years. In most locations, 
it is even scarce. 

CORN LEAF APHID ( Aphis maidis Fitch) 

New York. C. R. Crosby and assistants (August 28): Badly infested leaves 

received from Malone. (September ll): Badly infested cornstalk received 
from Hammond. Infested tassels of corn received from Oswego. 

Nebraska. M. H. Swenk (August 21 to September 20): Reports of injury to corn by 
the corn leaf aphid were received from Dixon and Furnas Counties. A complaint 
of the corn leaf aphid damaging corn was also received from Boyd County, 
while another Boyd County correspondent reported it working on feterita. 

Kansas. H. R. Bryson (September 23): This pest, which was so abundant on corn 
and sorghums during August, has practically disappeared. Ordinarily it can 
be found on immature sorghum heads at Manhattan at this time of the year, but 
such is not the case at present. 



-273- 



EURQPEAN CORN BORER ( Pyrausta nubilalis Hon.) 



Wisconsin. E. L. Chambers (September 27): Last year the European corn borer 
was found in a patch of sweet corn in Racine County and in two fields of 
corn in Manitowoc and Sheboygan Counties. These infestations were apparent- 
ly cleaned up. However, this year the borer was found in these counties and 
seven additional counties. The infestations were extremely light, but 
indicated the presence of the insect over a wide territory. A list of the 
infested townships is as follows;

ALJALEA 



ALFALFA TOE VI L ( Hyp era postica Gyll.) 



Nevada. G. G. Schweis (September 19): The alfalfa weevil is very abundant at 
Eallon and Reno; many adults are present. 

California. A. E. Michelbacher (September 20): Throughout its entire range in 
middle California larvae of the alfalfa weevil are rather hard to find. This 
is particularly true of the Tracy and Pleasanton areas. In the region about 
Niles the larvae are more abundant, although at the present time they are 
rather scarce owing to most of the alfalfa being cut for the fourth time. 
On the fourth crop in that area (Sept. 12) an average of 50 larvae were 
taken to 100 sweeps of the insect net. 



-274- 

A CURCULIO (Sitona cylindricollis Fab.) 

New England and New York. M. P. Jones (September): According to Robert Copple, 
B.P.I. , Middlebury, Vt . , this weevil has caused severe injury to young sweet 
clover this year, necessitating replanting in some places. Although the great- 
est damage is to seedlings, the weevil continues to feed on the foliage through- 
out the summer. Mr. Copple has found this weevil in the Lake Champ lain Valley 
of Vermont and New York, at Storrs, Conn., and Amherst, Mass. Identified by 
Mr. Buchanan May 10, 1932. First record in this country. 

GARDEN WEB WORM ( Loxostege similalis Guen.) 

South Carolina. F. Sherman (September 19): Usually gives trouble at this season 
and is now reported on turnips in the central section of the State. 

Indiana. J. J. Davis (September 25): The alfalfa webworm is doing much injury to 
alfalfa at Thorn town. 

SOYBEANS AND VELVETBEANS 

VELVET BEAN CATERPILLAR ( Anticarsia gemv.iatilis Hbn.) 

Florida. J. R. Watson (September 21): Velvet beans from Alachua County south are 
pretty thoroughly ragged by the velvet bean caterpillar. This is quite usual 
at this time of the year. 

Louisiana. R. C. Gaines (September 21): During the past week soy beans, in a 
number of fields in Madison Parish, have been almost completely defoliated. 

FALL ARMY WORM ( La-phygma frugiperda S. & A.). 

Florida. J. R. Watson (September 21): The fall fermyworm has been quite abundant 
in some sections of Polk and Lake Counties, where it has defoliated the grass 
cover crop in many groves. 

Mississippi. C. Lyle (September 23): A light infestation on corn was reported 

from Bogue Chitto, Lincoln County, on August 31. On September 15 a correspond- 
ent at Biloxi in Harrison County indicated that Bermuda grass in his pasture 
was severely injured. ■ 

Texas. R. K. Fletcher (September 5): The fall armyworm was noted as injuring 
late planted grain sorghum, 50 per cent of the young stalks having been 
injured in Burleson County.

CODLING MOTH ( Carpocapsa pomonella L.) 

Maine. C. 0. Dirks (September 5): Injury is more noticeable than usual through- 
out the State. 

New York. P. J. Parrott (September 21): The codling moth is very abundant. 

Pennsylvania. H. N. Worthier/ (September 26): The codling moth is very abundant 
in Adams County. Late attack has been severe. A heavy flight of moths in 
the last week of August lias resulted in i large increase in damage during 
September, with the prospect of a larger hibernating population than that of 
last winter. 

Maryland. E. N. Cory (September 25): The codling moth is very abundant. 

West Virginia. L. M. Peairs (September 21)" The codling moth is very abundant in 
northern West Virginia. 

Virginia. W. J. Schoene (September 23): Injury has been extremely variable. In 
some orchards the fruit is practically clean, whereas in other orchards the 
loss is very heavy. Generally speaking, injury is greater this year than in 
previous years. 

Indiana. J. J. Davis (Scottmber 22): The codling moth is very abundant, 
especially in the southern half of the State. 

Illinois. W. P. Elint (September 19): Damage continued serious up to the middle

Dean and Dr. P. L. Parker September 25 revealed the fact that the codling moth 
is worse in that district than it has been for 4 or 5 years. This condition 
is primarily due to the exceedingly hot, dry weather which that region 
experienced during June, July, and August. The codling-moth infestation is 
somewhat less in the Arkansas River Valley this year owing to the practice 
of more efficient control work. Owing to injury caused by the new generation 
of apple curculio adults ( Tachypterellus quadrigibbus Say), it has been 
impossible to control the codling moth by means of spray in northeastern Kansas 
during late summer.

and Lafayette) during September. Infestations" have been reported in horses, 
cattle, deer, hogs, sheep, goats, dogs, cats, and man. The monetary loss from 
dead livestock and the cost of treating infested animals has been severe. The 
outbreak was apparently due to the large number of dead animals in this area 
breeding flies, under ideal fly-breeding conditions -—warm wet weather. Five 
cases of myiasis in the human have come to my attention through veterinarians 
and physicians, these were all in Georgia. 



-233- 

Mississippi. C. Lyle (September 23): Reports have been received of infestation

abundant this year in southern Georgia and Florida, which afford ideal places 
for fly oviposition. 



MOSQUITOES (Culicinae) 

Maryland, Delaware and Virginia. F. C. Bishopt) (September 29): The outbreak of 
the serious disease of horses known as encephalonyelitis continues in Maryland, 
Delaware and Virginia. The fact that this disease has been transmitted 
experimentally by mosquitoes has directed much attention to the mosquito 
question. There has emerged from the salt marshes of the Central Atlantic 
States a series of heavy broods of salt marsh mosquitoes, which have given 
abundant opportunity for the spread of the disease if these species are concern- 
ed. These swarms of mosquitoes have greatly annoyed all classes of livestock 
and cut down their condition and reduced milk flow. They have also interfered 
with operation in farming and other industries.

INSECT f 1ST SURVEY B U h L E T I N 



<5s 



Vol. 13 November 1, 1933 No. 9 

THE MORS IMPORTANT RECORDS FOR OCTOBER, 1933 

The general situation regarding grasshoppers in the Great Plains has 
not materially changed since September. However, local outbreaks developed 
in Nebraska and threatening populations were observed in parts of Nevada 
and Colorado. 

Unusual damage to lawns by the green June beetle was reported in cities 
in Maryland and Kentucky. 

The Asiatic garden beetle is much more numerous on Long Island than it 
v/as at this time last year. 

A severe outbreak of the wheat wireworm developed late in the season in 
Vermont. 

Populations of chinch bugs in late summer were so extensive that ento- 
mologists of the East-Central and West-Central States held a conference dur- 
ing the month to organize for a possible control campaign next spring and 

summer. 

The codling moth situation has not materially changed since our last 
report, but the San Jose scale has been observed in increasing numbers from 
the New England States to Georgia and in Wisconsin. 

The tomato pinworm is again appearing in troublesome numbers in south- 
eastern Pennsylvania. In addition to damaging tomatoes grown under glass, 
it heavily infested numerous outdoor plantings. 

The pine needle scale lias been found unusually abundant from the New 
England States westward through Ohio to Wisconsin. 

During the month the gladiolus thrips was collected for the first time 
in Colorado. 

Serious damage by the tortricid leaf tier Platynota stultana Wals. was 
reported from -a large commercial rose-growing plant in northern Virginia. 
From 10 to 15 percent of the new growth was damaged. This is apparently the 
first record of this insect east of Mexico and California. 

The screw/situation in Texas is much more serious than it was last month. 
Throughout the Gulf coast district this insect is reported as being more 
abundant than it has been in several years. 

Stable flies were so numerous in the northwestern part of Florida that 
cattle spent the daylight hours in ponds and streams to avoid their bites, 
which restated in materially reducing the milk production.

GENERAL P E,E D E R S 

GRASSHOPPERS (Acrididae) 

Elorida. J. R. Watson (October): Grasshoppers, 'chiefly Schistocerca americana 
Drury,are very abundant, 

Illinois. W. P. Elint (October 24): Grasshoppers are relatively scarce. Condi- 
tions for egg laying have been very good, hut the small numbers of insects 
present this fall would not lead one to expect serious trouble in 1934. 

Minnesota. A.. G. Buggies ( October) : Egg surveys show few in the western part of 
the State, hut an increase in the eastern counties. Grasshoppers were "licked" 
badly in Minnesota this year; conditions are back to nearly normal. 

Mississippi. N. L. Douglas (October 16): The differential -grasshopper ( Melanoplus 



differential is Thos.) is moderately abundant in Yalobusha, Grenada, and 
Montgomery Counties. 

Nebraska. M. H. Swenk (October 20): A- local outbreak of grasshoppers occurred 

in western Perkins County during the middle of October; the insects were report- 
ed to be taking winter wheat in places. 

Utah. G. P. Knowlton (October 18): Grasshoppers are scarce to moderately abundant 
in northern Utah, where they are laying eggs. 

Nevada. G. Schweis (October 18): Grasshoppers in various portions of western 

Nevada have been under observation for the past several weeks; oviposition has 
been heavy. Many of these oviposition areas have been mapped and preparation 
will be made for early spring control programs. 

Colorado. G. M. List (October): Grasshoppers are moderately abundant in a number 
of localities. Egg laying will be rather heavy in limited areas in Boulder, 
Douglas, and Montezuma Counties. If good weather continues, there may be 
enough eggs deposited in a number of foothill localities to make control 
measures necessary next season. 

WHITE GRUBS ( Phyllophaga spp.) 

Maryland. ®. N. Cory (October 23): Many reports are coming in with regard to 
white-grub injury on lawns in various parts of the State. The infestation 
seems to be quite generally serious on the western shore. 

Kentucky. W. A. Price (October 24): White grubs are very abundant. 

GREEN JUNE BEETLE ( Cotin is nitida L.) 

Maryland. E..N. Cory (October 9): Pound in a lawn at Eccleston, Baltimore County. 

Kentucky. W. A. Price (September 23): Following heavy rains during early 

September, larvae emerged from lawns in Arcadia Park and crawled on their backs 
to the street. They were unable to crawl back over the curb stones and were 
thus trapped. Because of odor coming from the dead ones, the neighbors swept 
up the dead and living larvae each morning. More than a gallon of these grubs 



-29 7- 

Was removed, each day covering a period of .4 days during the week of September 
17. (October 24): Larvae of this pest -have rained many lawns in Lexington, 
particularly where grass cuttings have been thrown in- piles near the lawn. 

Alabama. J. M. Robinson (.October 20): The grubs are very abundant at Clanton 
where strawberry plants are being destroyed. 

JAPANESE BEETLE ( Popillia japonica Newm.) 



United States. U. S. Dept. Agr. Office of Information, Press Service (October): 
At Portland, Me., 52 Japanese beetles were captured during the season and at 
Waterville 139 beetles. At Salamanca, N. Y., 12 beetles were found. A 
vigorous eradication campaign to exterminate an established infestation is in 
progress at Erie, Pa. The points in Maryland at which 10 or more beetles were 
captured include Bethesda, Bladensburg, Chevy Chase, Hyattsville, Riverdale, 
Silver Spring, and Hurlock. At Keyser, W. Va. , the capture of 25 beetles is 
reported. 

Vermont. H. L. Bailey (October 24): The Japanese beetle is scarce. One, specimen 
was found in a trap at Burlington. This was the only one recorded ill the 
northern half of Vermont. 

New Jersey. C. C. Hamilton (October 7): Japanese beetle grubs are common and 
doing damage. 

ASIATIC BEETLE ( Anomala orientalis Waterh.) 

New York. C. H. Hadley (October 23): The Westchester County Farm Bureau agent 
reports that the oriental beetle is numerous in the southern half of West- 
chester County.

Connecticut. W. E. Britton (October 24): -This is the first evidence of injury 
by this beetle in New Haven. 

New York. C. H. Hadley (October 23): Grubs are more numerous at Jericho this 

fall than at this time last year. At Locust Valley we are finding an average 
of 20 grubs to a square foot in ground that has been cultivated all the season. 

WHEAT WIREWORM ( Agriotes mane as Say) 

Vermont. H. L. Bailey (October 24): Reports have been received of serious damage 
to potatoes by wheat wireworms in Franklin and Washington Counties. Earlier 
reports of severe damage to corn in Windham County indicate generally heavy 
infestation in the State. 

CUTWORMS (Noctuidae) 

Missouri. L. Haseman (September 22): Adults of the black cutworm ( Agrotis ypsilon 
Rott.) are quite abundant. Variegated cutworms ( Lyco-photia margaritosa saucia 
Hbn.) are rather abundant and heavily parasitized by a fly. 



-298" 

Kansas. H. R. Bryson (October 24): Cutworms ( Feltia due ens Walk.) have "been 
unusually abundant this fall in the vicinity of Manhattan. Individuals were 
sufficiently numerous to check the growth of new shoots- arising from the crown 
■of alfalfa plants after the crop was "mowed in the middle of September. Recent 
observations following cold nights reveal a large number of dead larvae; and 
at this writing all have disappeared* ! 

MONARCH BUTTERFLY (Banaus meni-ppe Fab . ) 

Maryland. E. N. Cory (October 4): A flight of monarch butterflies was located 
on September 30 at Point Lookout, the southernmost tip of Maryland along the 
Potomac River. On October 2 the large flight settled at Piney Point near the 
lighthouse, the keeper of which informed us that the butterflies appeared 
there annually. This flight took off across the Potomac River on October 4 at 
8 a.m. The butterflies came in in the late afternoon in such numbers that the 
people walking about the grounds of the lighthouse were constantly being 
struck by the flying butterflies. At 5 o'clock, when the writer uas there, 
the butterflies had begun to cluster on the southern and southeastern sides 
of cedar trees and locust bushes. A large number were collected, all of 
which appear to be newly emerged or at least undamaged specimens. . 
F. C. Bishopp (September 13): Th monarch butterfly was observed in large 
numbers on tree trunks near the water in Anne Arundel County, near Annapolis. 

Texas. 0. G-. Babcock (October 21): There was a general southward migration of 
the monarch butterfly during the week of October 1 to 7. They were common 
everywhere over the range country and gathered in considerable numbers upon 
flowers about residences. There are now only a very few left. 

A FYRALID ( Pachyzancla phaeopteralis Guen.) 

Louisiana. C. E. Smith and P. X. Harrison (October 28): The larvae have been very 
destructive to pasture and other sod grasses over considerable areas of 
southern Louisiana during September and October. It was first observed in 
St. James Parish on September 19. Reports have been received that the injury 
was first noticed about September 1. . On October 25, Mr. Callaway .reported . '. 
that large numbers of the moth were present in his parish during the last part 
of September and entered residences and public building's in annoying numbers. 
The larvae continued damaging sodland grasses until about October 15, at 
which time a good rain occurred. During the latter part of September, a report 
of severe damage to pasture grasses was received from Dutchtown (Ascension 
Parish), On the night of September 20, large numbers of the moth were 
observed hovering over lawns, golf courses, etc., at Baton Rouge. By October 
15, larval damage to these sod grasses was in evidence, and by the 20th. 
considerable areas had been completely void ■ of all green growth. The damage 
has continued and at this time the sods of many lawns and considerable areas 
of other sodlands appear as dead - nothing green in evidence remains. For 
several days now a few moths have been issuing from this destructive brood 
at Baton Rouge.

CHINCH BUG ( 31 is sus leucopterus Say) 

Ohio. T. H. Parks^CQ^tober 23): The chinch but, is more abundant than usual. 
The outstanding/injuries of the year were caused ~oy the codling moth and 
chinch bug. The months of June and July were very favorable for chinch bugs, 
which develox^ed a heavy second generation. 

Illinois. W. P. Elint (October 24): Fall flights continued during the early 
part of the month and ©.bout SO percent of the bugs are now in hibernation. 
The weather was very favorable for hibernation flights, and there will 
probably be only a moderate winter mortality. 

Iowa. C. J. Drake (October 26): The chinch "bug situation in Iowa appears very 

serious. There has been a considerable spread by the adults of both the first 
and second generations. Vv'e expect a further spread again next spring. Biotic 
conditions have been very favorable for the chinch bug this summer and fall. 

Iowa. H. E. Jaques (October) : The chinch bug is very abundant in the south- 
eastern corner of the State from Union County eastward a.nd covering the 
southern two tiers of counties. The insect has also been observed in moderate 
numbers in the third tier of counties from Warren County eastward. 

Missouri. L. Kaseman (September 22): Over the northern and northeastern part of 
the State the situation is very threatening. The chinch bug is more abundant 
in corn than for many years.

"..ere very abundant in alfalfa fields. 

Oklahoma. C. F. Stiles (October 2): This insect has caused considerable damage 
to cotton throughout some sections of the State. 

H. G. Young (October 4): The cotton boll worm was more numerous in south- 
eastern Oklahoma during the past season than during any of the recent years. 
In many fields it caused considerably more damage than the weevil this year. 

EUROPEAN CORN BORER ( Pyrausta nubilalis Hbn.) 

Vermont. H. L. Bailey (October 24): A survey started recently in Chittenden 
County shows pooulations of from 2 to 20 larvae per square rod in debris of 
old cornfields and greater numbers in fields of early-planted corn. 

Massachusetts. A. I. Bourne (October 24): The European corn borer is moderately 
abundant generally, and is present in greater abundance than last year, 
particularly in the Connecticut Valley. In a number of home gardens the 
infestation was severe enough to cause appreciable loss. This record is of 
interest locally in the Connecticut Vallev since it is the first season that 
any appreciable amount of damage has occurred there. 

FALL ARMYUORM ( Laphygma fruglperda S. & A. ) 

Florida. J. R. Watson (October 25): The fall armyworm is still in evidence, 
although probably not so abundant as it was in the late summer. 

Mississippi. C. Lyle and assistants (October): The southern grass worm was 
moderately abundant at Ocean Springs in September. 



-301- 

Missouri. L. Haseman (September 22): Adults of the fall arrnyworm are quite 
abundant. 

Oklahoma. C. F. Stiles (October 2): The fall arrnyworm has been reported in 

several of the western counties and is doing serious damage to the early-sown 
wheat, especially the wheat near grown-over fence rows and roadsides. 

ALFALFA 

ALFALFA WLFVIL ( Hypera postica Gyll.) 

California. A. E. Michelbacher (October 20): Larvae are very difficult to find 
in the region about Tracy. From 700 sweeps in three different fields only 
one larva was collected. For the most part few adults were taken, although 
in one field an average of 13 adults per 100 sweeps was obtained. Larvae 
and adults are somewhat more abundant in the Pleasanton area. On the 1G th- 
an average of 25 larvae and 4 adults were collected per 100 sweeps, in one 
field, although the count for the district as a whole seemed to be somewhat 
lower. In the territory about Files the population has built up some on the 
fifth crop, which is reaching maturity. The heaviest infestation observed on 
October 18 showed an average larval count of 200 per 100 sweeps. The average 
adult count was two. 

CLOVER LjJAF WEEVIL ( Hyp era punctata Fab.) 

California. A. E, Ivlichelbacher (October 20): Some adults have been collected 
in the regions about Tracy, Pleasanton, and Miles. A few larvae have also 
been taken, and are apparently most abundant about Niles, where I would say 
that about 10 were gathered per 100 sweeps. This is only an estimate, as no 
accurate counts were made. 

COWPLA 

CO'TPFA CURCULIO ( Chalcodermus aeneus Boh.) 

Mississippi. C. Lyle (October 23): Serious infestations on cowpeas were recently 
reported from Ocean Springs, Jackson County, and V'althall in Uebster County.

APILE 

CODLING- MOTH (Caxpocapsa pomonella L.) 

New York. P. J. Parrott (October 23): The codling moth is very abundant in 
western New York. 

Maryland. E. N. Cory (October 21): The codling moth is very abundant. 

Ohio. T. H. Perks (October 23): The codling moth is very abundant. This is the 
worst infestation we have had in many years. Injury persisted throughout 
September and some worms were entering apples as late as October 5.^ ^The 
months of June and July were very favorable for the codling moth; w^s 
permitted a heavy second generation. 



-302- 

Illinois. 17. F. Flint (October 24): Codling moths continued to hatch, in the 

central and southern sections of the State during the latter part of September. 
Very large numbers of the larvae are going into winter quarters in all the 
orchard sections of the State. 

Kentucky. W. A. Price (October 24) '■ The codling moth is very abundant. 

South Dakota. H. C. Severin (October 5): The codling moth is very abundant. 

Missouri. L. Easeman (September 22): Codling moth damage is severe, especially 

in the northern part of the State. Pupation in central ivlissouri ceased by 

September 5 - 10. Pew moths still visit bait pans; worms are no longer enter- 
ing fruit. 

New Jersey. T. J. Headlee and assistants (October 7): The codling moth is very 
abundant in some sections. 

Nevada. G-, Schweis (October 18): Injury is more apparent than in the past 

several years, in western ITevada. A survey made recently of several unsprayed 
orchards shows nearly 100 per cent infestation. 

Utah. C~. P. Kncwlton (October 18). The codling moth is moderately to very 

abundant in northern Utah, where considerable injury has been done to the light 
apple crop. 

California. S. 0. Issig (October 21); The codling moth is moderately abundant. 
Stewart Lockwood (October 9): The codling moth has been increasing as a pest 
of both per-rs and apples. This is due to two factors: Control measures were 
not applied, and, because of poor returns, great quantities of pears have not 
been marketed, with a resulting build-up in the population. 

A TBJPOID MOTH ( Lymnaecia phragmitella Staint . ) 

Massachusetts. A. I. Bourne (September 25): On about September 20 the drop 

apples in one block of Mcintosh were found to be rather badly riddled by the 
caterpillars of some lepidopterous species. The orchardist had mulched his 
trees rather heavily with flags which he cut during the summer in a swampy 
area near his orchard. This species is recorded as one of the most common 
insects attacking cat-tail. (September 23): This species has been verified 
^oy an e:cpert as Ly mnaecia , and probably phragmitella Staint. 

APPLP LZAP SKELSTQHIZBH ( Psorosina h ammondi Pi ley) 

Kentucky. W. A. Price (September 23): Specimens of the apple leaf skeletonizer 
were received from two orchards near Pa due ah with the statement that they were 
ruining the trees.

occurred at Columbia. 

SAN JOSE SCALE ( Aspidiotus pernio iosus Comst.) 

Massachusetts. A. I. Bourne (October 24): The San Jose scale has been found on 
fruit from a number of orchards in various sections of the State. Enough of 
this has been found this year to give strong indication that the pest is some- 
what on the increase in many orchards. 

Georgia. 0. I. Snapp (October 20): The San Jose scale on peach trees at Fort 
Valley is more abundant than it was last season. Heavy infestations in some 
orchards are necessitating an unusually early application of oil emulsion. 

Wisconsin. E. L. Chambers (September 27): Despite a 90 per cent winter-killing 
of the San Jose scale in most sections during the past winter, these insects 



-304- 

are apparently getting well established again, and new infestations have "been 
found by the nursery inspectors in the 12 southern counties now known to have 
infestations. 

SCURFY SCALE ( Chionaspis furfura Fitch) 

North Carolina. Z. P. Metcalf (October 25): The scurfy scale is abundant on apple 
at Blowing Rock. 

EUROPEAN RED HITS ( Paratetranychus pilosus C. & F.) 

California. S. Lockwood (October 9): The European red mite was somewhat more 
than normally abundant in the principal pear-growing sections of the State. 
This may have been due to the cool, late spring of this year. 

PEACH 

PEACH BORER (Ae geria exitiosa Say) 

New York. F. J. Parrott (October 23): The peach borer is very abundant. 

Georgia. 0. I. Snapp (October 20): Moth emergence was practically completed in 
the field at Fort Valley o-j September 22, much earlier than usual, and .the 
pupation season started earlier than usual. The insect was less abundant 
than usual on account of the work of predators in 1932. 

Mississippi. C. Lyle (October 23): Complaints of infestations have recently been 
received from various sections of the State. 

Colora.do. G-. M. List (October): The peach tree borer has increased a great deal 
in plantings of sour cherry in northern Colorado during the past two seasons. 
Ordinarily but few of the growers in this section treat for this insect, but 
this sec son it is advisable for most of them to use treatment. 

LESSER PEACH BORER ( Aegeria pictfpes G. & R.) 

Mississippi. C. Lyle (October 23): A grower at Shuqualak in Noxubee County 
recently reported that his peach trees had been injured.

Georgia. 0. I. Snapp (October 20): Pupation has ceased at Fort Valley; all 
larvae are now in hibernavtion. 

Ohio. T. H. Parks (October 23): The oriental fruit moth is moderately abundant. 
Quinces have been ruined and peaches along Lake Erie are moderately infested. 
There are/ peaches elsewhere in Ohio this year. 

Kentucky. 17. A. Price (September 23): The oriental fruit moth has been very 
scarce in Kentucky throughout the season. It has been impossible to find 
wilted twig material sufficient to make a satisfactory recovery count in the 
orchards where Macrocentrus ancylivorous had been liberated last yea.r. 

Mississippi. C. Lyle (October 23): Peach twigs showing injury were recently 
received from Drew, Sunflower County.

Joseph, September 11, included some false chinch bugs. 

Mississippi. C. Lyle (October 23): The false chinch bur was reported early in 
October as seriously infesting turnips in a garden at Starhville, Oktibbeha 
County. An investigation showed that the infestation was rather spotted 
throughout the planting. 

POTATO A?:D TOMATO 

TOMATO PUT WORM (G noririo schema lycopersicella Busck) 

Pennsylvania. C. A. Thomas (October 21); The tomato pin worm has again been 

found in southern Chester County, where it seems to be well established in a 
number of greenhouses from Avondale east as far as Brandywine Summit, in 
Delaware County. Numerous outdoor plantin.es we T, e found to be infested, and 
in some the injury was so severe that many of the tomatoes dropped from the 
vines. ^lie infestation of the greenhouses has so far been less severe. The 
exact limits of the distribution have not yet been determined. Scarcely any 
parasitization has been noted. 

POTATO FLEA BE2TLE ( Epitri x cucuraeris Harr. ) 

Colorado. G-. M. List (October): The potato flea beetle has been about normal in 
numbers in Weld and Morgan Counties, where the chief injur}* - occurs, but 
apparently has been causing much more wo in track on potatoes than usual in 
Si Paso and Montezuma Counties. 

STRIPED BLISTER BEETLE' ( Epicauta vittata Fab. )

abundant. All stares from second-instar larvae to adults were found in the 
field October 15. 

Massachusetts. A. I. Bourne (October 24): The Mexican bean beetle has spread well 
over the State generally. In the new Sections where it has just appeared it 
has done considerable damage, chiefly because it caught the growers more or 
less unprepared. In those sections where it has been established for several 
years it is no more abundant than last year.

Ohio. 72. 17. Mendenhall (October 21); Rie strawberry leaf roller is very bad in 
strav/berry plantations in Miami County and especially in the Brandt locality. 
This seems to be the third brood. 

MUSHROOMS 

SPRDTGTAILS (Collembola) 

Pennsylvania. C. A. Thomas (October 21): Snrin?tails have been very destructive 
to newly planted mushroom spawn this fall; probably the most of these entered 
the mushroom houses with the wet manure. Most of those damaging the snawn 
have been determined by Dr. Polsom a,s a species of P:'oisotoma very close to 
P. thermophila Axels., perhaps a variety of that species. A sli jht amount of 
injury has been done in a couple of mushroom houses near Reading by 
he oi docvrtus lanugino su s (Gm.el. ) [Pull.., which ate quite" large holes into the 
caps aid stems of the growing mushrooms. This is the species that has done 
considerable damage in nrevious rears in nmshroom houses at Barbei-ton^ Ohio.

collection and examination of cotton blooms from' the' plats at Chapman Field 
were continued throughout the month, with negative results. From time to time 
okra and other hibiscus blooms have also been examined. On August ?3 two pink 
boll worm larvae were found in hibiscus blooms. The plant on which the insect 
was found is a hybrid, Hibi scus rosa- sinensis . Immediately after this finding, 
two inspectors began an intensive examination of hibiscus blooms, and at this 
time 10,000 have been inspected without any further specimens having been 
found. It would therefore appear that there was no general infestation in 
hibiscus.

gardens near Chester, Pa., and in a 2-acre dahlia field at Media. It was also 
stippling chrysanthemums in a greenhouse at Snitland, Md. 

MITES ( Tar son emus spp. ) 

General. F. F. Saith (September): The broad mite, Tarsonerms latus 3ks. t was 
injuring dalilias in a field and Gerbera plants in a greenhouse at Media, Pa. 
Apparently the mites moved from the Gerbera to the dab-lias in the early spring 
during the period that the dahlia cuttings wore being made, and were later 
taken to the field. Apparently this is a new State record. An undescribed 
Tar son emus was associated with T. latus on dalilias in this infestation. The 
mite was also found associated with T. pallidas Bks. on specimens. of 
Delphinium belladonna sent in from '[ingsford, Me. Infestations of this 
species alone, and apparently not associated with pallidas or latus, were 
found on chrysanthemum leaves at Baltimore, Md. , Alexandria, Va. , and in the 
District of Columbia; also on Delphinium b elladonna in a field at Snitland, 
Md. Chrysanthemum leaves are Injured on the lower surface, then become 
bronzed and brittle, much as when injured by T. pallidus . O'n delphinium the 
blackening and dying of leaves appears very pronounced, but there is no marked 
leaf or flower- bud distortion like that caused by T. pallidus . This mite also 
apparently survived the winter and summer on delphinium. 

Washington. W. W. Baker (September): Terminal shoots of nettle ( Urtica ) collect- 
ed at Puyallup were found to be heavily infested with mites, which appear to 
be T. pallidus . •

Virginia. C. A. Weigel ( September) •! A tortricid leaf tier was found injuring 10 
to 15 percent of the new growth on approximately 100,000 roses in a greenhouse 
range at Alexandria. The larvae draw two leaves together, or fold over the 
edges of individual leaves, usually severing the petioles of the leaflet and 
causing it to die. Some feeding takes place on the inner side of the folded 
leaf; also flower buds are sometimes eaten into on the side and tender growths 
are cut off. According to August Busck, this is the first record of this 
species outside of Mexico and California, where it is a serious pest of oranges, 
roses, and peppers, and occurs on other plants.

MOSQUITOES (Culiclnae) 

Florida. J. it. Watson (October 25): Following the hurricane of September, 

mosquitoes were very abundant, but with the drier weather they are gradually 
thinning out. Their rice in numbers followed the hurricane in a very few days, 

Texas. E. W. Laake (October 24): Anopheles sup. and the yellow fever mosquito 
( Aedes aegyp t i L.) have been very abundant in Dallas during October. An 
unusual number of cases of malarial fever have been contracted in Dallas 
during the month. 

FUSS CATERPILLAR (Megal opyge opercular is S. & A.) 

Mississippi. C„ Lyle (October 23): Larvae were received recently from Liberty 

in Amite County and Ludlow in Scott County, the sender in each case reporting 
that a. person had been severely stung. 

Texas. 1. W. Laake (October 24): The stinging caterpillar has been quite abun- 
dant over central, northern, and northeastern Texas. No complete defoliation 
of trees has been observed, but many trees of Dallas arid other cities have 
assumed a ragged appearance during the month as a result of the feeding of 
numerous larvae. The Dallas City Forestry Department sprayed several 
thousand trees in the State Fair grounds, and, according to the report of 
the City Forester of Fort Worth, over 20,000 gallons of spray was used on 
shade trees in that city. Numerous cases of stings by this caterpillar have 
been reported in Dallas and other cities in the affected area. 
F. L. Thomas (October 28): Very abundant in Ft. Worth, Dallas, and other 
points in northern Texas on hackberry and oak especially. Also recorded on 
redbud and peach. 

CRINKLED FLANNEL MOTH ( Logoa crispata Pack.) 
SADDLE-SACK CATERPILLAR ( Sibine stimulea Clem.)

Andalusia. Several members of one family were stung. 

SAND FLI5S (Culicoides spp.) 

Georgia. W. E. Dove and D. G. Kail (September 29): Two species of sandflies 
which normally occur only during the summer months, C. dovei Hall and C. 
melleus Coq. , are very annoying and abundant at Savannah.

were reported at Montpelier and Brandon. 

RAT FLEA (Cerato phy llus fasciatus Bosc.) 

Alabama. -J. M. Robinson (October 20): The rat flea is very abundant at Clio. 

It is also very abundant in southeastern Alabar.a, causing many active cases 
of typhus fever. 

CATTLE : . . 

SCREW kVOm; (Coc hliomyia nacell aria Fab . ) 

Mississippi. C. Lyle and assistants (October): Southern Mississippi seens to 

have a very heavy infestation of screv- worms this fall. Numerous conplaints 
cone from all sections of the Wiggins territory. Some farmers state that 
sheep raising will soon be a thing of the past if the screw worm continues. 

Texas. E. W. Laake (September): Rains during August and early September in 
various sections of the southern and southwestern parts of the State have 
made conditions ideal for the development and activity of the screw worm. 
As compared with other months of this season, screw worm cases in domestic 
animals have more than doubled in most of these areas during September. In 
the Edwards Plateau region, which is primarily a sheep and goat country and 
where shearing was under way during the entire month, an accurate record on 
approximately 70,000 domestic animals of all classes showed an increase of 
nearly 200 per cent in the number of screw worm cases as compared with the 
number of cases recorded for the same number of animals daring any other 
month of this season. Shear cuts were partly responsible for the high screw 
worm incidence in sheep and goats, but other classes also showed an increase 
of almost 100 percent in the number of cases of myiasis during September. 
In the Gulf coast section screw worms were reported to be more abundant this 
fall than at any other time in several seasons. Stockmen along the coast in 
Jackson County reported a 35 percent infestation in their cattle and calves. 



STABIE FLY ( Stompxys c ale it ran s L . ) 

Georgia. W. E. Dove (September 29): On the islands and along the coast this 
species has become very abundant and annoying. 

Florida. 17. V. Kin- (October 6): Very large numbers of the stable fly, or "dog 
fly" as it is known in Florida, have been reported from some localities of 
the northwestern coast section of Florida. .A correspondent writes of swarms 
of these flies which run cattle into the lakes, creeks, and bayous, close 
up summer resorts, etc. "Dairies have their production lowered from 20 to 
50 per cent in a week's time, i'ensacola Beach is practically ruined after 



-318- 

the beginning of the dog-fly season. It is absolute torture to stay in 
the open if you are at all quiet during this period. Fishermen many miles 
from shore have difficulty in staying out during a land breeze. Bathers are 
particularly attractive, the pest preferring to feed on a wet skin, and one 
must keep all of one's body immersed continuously or "be bitten by these 
voracious pests." 

Iowa. 77. G-. Bruce (October 30): Flies are still annoying stock at Ames. 

A BUFFALO GHAT (Si mulium venustum Say)

L. were emerging from soil, out of doors, October 30 at Ames. Previous to 
October 28 the last observation of the activity of the flies was on October 4. 
Four thousand eggs of G. in testinalis , from 17 heo.d of horses, yielded an 
average viability of 42.13 percent. 

Utah. G. F. Znowlton (Octoher 23): Botfly eggs on the legs were fairly abundant 
on a few horses examined at Hyde Park. 

BUFFALO GHATS (Simuliidae)

The grubs are very noticeable from the holes they make when they leave the 
chestnuts for pupation. 

HIES BEETLE ( Serine stes vulp inus Eab.) 

Ohio. T. H. Parks (October 25): A serious outbreak is occurring in a packing 
house in Columbus. The larvae and beetles are in cured hams and in the 
timbers of one of the rooms. 

MISCELLANEOUS STORED GRAIN PESTS 

South Dakota. H. C. Severin (October 5): A terrific outbreak of stored grain 

insects occurred over the State in general. Insects concerned are principally 
the granary weevil ( Sitophilus granaria L.), saw-toothed grain >•..., • 
beetle ( Cryzae ohibn s sur inameasi s L.), square-necked grain beetle ( Catbartus 
quadricollis Guer.), and confused flour beetle ( T r ib o 1 iu m c o nfusum Duv.). 

Colorado. G. M, List (October): The more common practice of carrying over grain, 
which has been followed the last two or three years, apparently has been 
responsible for a marked increase in stored-product insects, the granary 
weevil being the most common one reported. Many small holdings of grain are 
being badly damaged.

INSECT PEST SURVEY BULLETIN 



Vol. 13 Summary for 1933 No. 10 



INTRODUCTION 



The winter of 1932-33 was generally milder than the average, 
with deficient rainfall in some sections, especially in the Southwest 
and the Great Plains. January was warm and dry, especially in the 
upper Missouri Valley; February was nearer normal, with some sudden 
and severe cold waves, and unusual cold in the mountain and Pacific 
States. 

Spring was somewhat above normal in temperature, especially 
March. Rains were generally abundant in the eastern half of the 
country, and delayed farm work in the eastern part of the Corn Belt; 
in many parts of the West the moisture deficiency was unrelieved. 

June was warmer than normal, especially in the Plains States, 
and continued drought in that region reached the stage of crop dis- 
aster in many localities. Many temperature records were broken. 
Farther east conditions were nearer normal, though rainfall was 
variable and often light. July was above normal in temperature ex- 
cept along the Atlantic coast; rainfall was quite variable, but more 
plentiful than in June. 

Late summer and early fall were marked by some relief from 
drought in the plains region and by an unusual number of tropical 
hurricanes, some affecting cur eastern coast. These conditions are 
reflected in insect pest abundance in many cases, as brought out in 
the following pages.

GRAS SHOPPERS 

Although the grasshopper situation was much less alarming in the fall of 
1932 than it was in the fall of 1931, the weather was extremely favorable dur- 
ing the hatching season and winter and spring mortality was extremely low in 
the Great Plains, the egg survival running from 90 to 95 percent over roost of 
the territory. Heavy infestations occurred along the northern half of Montana 
east of the Rocky Mountains into the western half of North Dakota and across 
South Dakota in a hand extending from the northwest to the southeast. A large 
area of heavy infestation occurred in north-central Wyoming and in the north- 
eastern corner of that State, with an area of lesser infestation along the 
foothills of the Rocky Mountains. Beyond these areas moderate infestations 
occurred over the greater part of Montana, the northern two thirds of Wyoming, 
the southeastern corner of Idaho, and in northern Utah, the remainder of North 
and South Dakota, and along the northern border of Nebraska. In Minnesota, 
moderate infestation occurred in the northwestern part of the State, with more 
intense infestation in the northeastern and central parts. Somewhat severe 
damage was also recorded from the northeastern half of Wisconsin, practically 
the entire northern peninsula of Michigan, and the northwestern corner of the 
lower peninsula. Control campaigns were put on in several States as far as 
the extremely depleted finances of the farmers would allow. Scattered out- 
breaks were reported in Iowa, Oklahoma, Mississippi, Texas, Colorado, and 
Nevada. Populations continued heavy throughout the remainder of the summer, 
and there was considerable migration. The dominant species in the most 
heavily infested territory was the lesser migratory grasshopper, Melanoplus 
m exicanu s Sauss. Pall egg surveys in northern plains indicate a very serious 
situation. The fall survey of this area for 1932 showed only 2 counties 
(in southwest North Dakota) which had egg populations sufficiently heavy to 
threaten from 50 to 100 percent of the crops this year in this entire terri- 
tory; this year 35 counties are as heavily infested as this. Infestations 
running over 25 percent were found in 24 counties in the fall of 1932 and in 
93 counties this fall. The most notable increase in seriously infested 
territory is across northern Montana and in north-central and northeastern 
Wyoming. This year comparatively heavy infestations are also reported from 
southeastern Idaho and northeastern Minnesota, with a very heavy infestation 
in northern and southwestern North Dakota and in cenlWal South Dakota. 
Similar heavy infestations extend well northward into Alberta, Saskatchewan, 
and Manitoba in Cana.da. 

CHINCH PJG 

The chinch bug ( Bli ssus leucopterus Say) overwintered successfully over 
the greater part of its normal habitat and also somewhat north of this region. 
Heavy rains late in April and early in May materially checked its development 
in many sections, particularly in the eastern part of the territory. Late in 
May and in June heavy populations built up in northern Missouri, central 
Illinois, northern Indiana, and west-central Ohio. During July and August 
severe depredations occurred from northern Missouri eastward to Ohio, with 
less important outbreaks extending from east-central Texas, across central 
Oklahoma and eastern Kansas, to southeastern Nebraska, thence eastward across 
southern Iowa to southern Michigan. In the fall generally heavy populations 
were reported throughout this entire territory; and an isolated heavy infes- 
tation occurred in ten counties in Pennsylvania extending from Adams County 



-327- 



on the south-central "border of the State northward to Columbia and Union 
Counties. In parts of Hew England and southern New York there were also 
unusual but light infestations. During September heavy flights to hiber- 
nating quarters were quite generally reported; and severe infestations are 
anticipated from Missouri eastward into Ohio, with a possibility of infes- 
tations over a much wider territory. During the late fall and early winter 
months entomologists of the infested States were organizing for winter 
destruction of hibernating quarters and a summer campaign for control of 
the imminent outbreak. 

HESSIAN FLY 1 

Infestations by the Hessian fly (P hytopha^a destructor Say) in young 
wheat in the fall of 1933 were very light throughout most of the winter- 
wheat belt of the Central and Eastern States. The only area containing 
moderate to heavy infestations in many fields is southeastern Missouri, in- 
cluding the southernmost east-central counties, with considerable damage to 
some early-sown fields, especially in counties near the Mississippi River. 
Occasional fields containing light to rather heavy infestations occur in 
the following areas: A few counties of south-central Nebraska; south- 
eastern Kansas, including the southernmost of the northeastern counties and 
the easternmost of the south-central counties; central and southwestern 
Missouri; south-central Tennessee; and south-central Pennsylvania. The 
factors responsible for the generally low infestation this fall are (l) the 
comparatively small number of puparia passing the summer in the stubble and 
(2) shortage of moisture in the greater part of the winter-wheat growing 
area during summer and fall. The latter factor affected Hessian fly abun- 
dance in three ways - inhibition of fall activity, restriction of volunteer 
wheat growth, and delay of wheat-planting operations so that the bulk of the 
crop came up late enough to escape infestation. There may be material 
injury to the 1934 crop in southeastern Missouri. Scattered fields may 
also be considerably affected in south-central Nebraska, southeastern Kansas, 
central and southwestern Missouri, south-central Tennessee, and south- 
central Pennsylvania. In the remainder and by far the greater part of the 
winter-wheat belt, however, injury of any consequence to the current crop 
is very unlikely. 

For purpose of comparison with the survey made last year we are append- 
ing a table of the State a.verages obtained by taking an average of the 
regional averages.

EUROPEAN CORN BORER 2 

Despite the general decrease in the population of the European corn 
borer ( Pyrau sta nubilalis Hbn.) in New York, many farmers complained of 
losses to early-planted sweet corn. The average plant infestation in 20 
fields in nine counties "bordering Lakes Ontario and Erie was 35.6 percent, 
and the average infested plant contained approximately 1.5 borers. The loss 
in ears for the 20 fields amounted to approximately 28 percent. The adults 
deposited eggs in comparatively large nvmbers, resulting in a moderately 
severe infestation in the vicinity of Toledo. In the other Ohio counties, 
however, the corn was delayed by lack of moisture, and because of its small 
size during the oviposition period few eggs were deposited upon it. The ex- 
tremely warm, dry weather which prevailed throughout the oviposition period 
killed many eggs before they could hatch. Unfavorable conditions similar to 
those in Ohio prevailed over most of Michigan, although the sandy soil in 
that State absorbed the heavy spring rains more rapidly than did the Ohio 
soils, and it was possible to plant corn at the usual time. Extremely warm, 
dry weather, however, during the oviposition period killed many eggs. The 
fields examined were almost all late-planted and conseqixently were less 
heavily infested than the early-planted fields. Had it been possible to con- 
duct the Michigan survey two weeks earlier, it is quite probable that the 
1933 infestation survey data from that State would have been approximately 
equal to those of 1932, 

The following table gives the average numbers of borers per 100 plants 
for the nine-year period 1925-1933, based on examinations made in comparable 
counties:

CORN EAR WORM 

The corn ear worm (H elioth is obs oleta Fab.) was much more abundant than 
usual throughout the South. At points in the Sulf region 80 percent of the 
winter corn was rejected at the packing shed on account of infestations and 
100 percent infestation was quite general. Throughout the Middle Atlantic, 
East Central, and West Central States infestations were about normal, while in 
Hew England and the North Central States damage was decidedly less prevalent 
than was the case last year. In the South, in addition to attacking sweet 
corn, the larvae seriously infested tomato. In North Carolina they did some 
damage by burrowing into half-grown peaches; this was usually a consequence of 
cutting vetch in the poach orchards. 

ARMYWORM 

The first adult armyworm ( Cirphis u nipuncta Haw.) of the season to be 
recorded was taken in a light trap at Clemson College, S. C, March 10. During 
the first week of April heavy flights of moths occurred in central Illinois. 
Late in May the first outbreaks of the season were reported from St. Marys 
County, Md. , and James City County, Va. Late in May and throughout June out- 
breaks were reported from West Virginia, Pennsylvania, Tennessee, Wisconsin, 
and North Dakota. 



CUTWORMS 

During the last week in March considerable damage was done to wheat in 
Kansas and Oklahoma by the army cutworm ( Chorizagrotis auxiliaris Grote) . 
This cutworm also damaged fall-sown alfalfa, oats, and vetch. The popula- 
tion at Manhattan averaged 45 cutworms per square foot, with a maximum record 
of 90. This species was found in wheat fields in Cascade County, Mont. 
After the spring advanced the usual reports of cutworm injury were received 
from practically the entire country. During May the army cutworm was again 
reported damaging small grain in South Dakota; and in early June, flights of 



-330- 
th© moth were observed in Nebraska, indicating that this species has been 
prevalent in that State this year. The pale western cutworm ( ?orosag;rotis 
orthogonia Morr.) was much less abundant this year than last in Montana. During 
June the black cutworm ( JLyr otis yq si Ion Rott.), locally "Known as the overflow 
worm, appeared in outbreak numbers on bottom lands that had been overflowed 
during March in Ohio, Indiana, Illinois, and parts of Tennessee. In Ohio and 
Indiana entire fields of corn were completely destroyed. 

LESSER CORF STALK BORER 

The lesser corn stalk borer ( El a smopalpu. s lignosellus Zell.) appeared in 
destructive numbers along the Atlantic seaboard from the Eastern Shore of 
Virginia to northern Florida and around the Gulf to the Mississippi River, ex- 
tending northward to central Mississippi and Alabama. Heavy damage was occa- 
sioned to corn, with some damage to sugarcane, field peas, cowpeas, Irish 
potatoes, beans, and strawberries. At several points in northern Florida from 
70 percent to complete loss of the late-planted corn crop was sustained, the 
plants breaking off in heavy wind.. In some places in Georgia this insect, 
associated with the southern corn stalk borer ( Diatraea crambidoides Grote) , 
destroyed half of the corn crop. 

ALFALFA WEEVIL 3 

The alfalfa weevil ( Hypera postica Gyll.) survived the summer of 1933 in 
exceptional abundance in Salt Lake and Sevier Counties, Utah, and in Churchill 
County, Nev. Its numbers were low at the beginning of the season because of 
unusual winter mortality, and this was the more important because a. backward 
spring suppressed the oviposition -until a late date. These conditions were off- 
set, however, by a very warm, bright summer and a high winter death rate of the 
parasite Eathyplecte s curculioni s Thorns. The outlook, accordingly, subject to 
the developments of the winter, is for damage of economic proportions in the 
localities mentioned above, and elsewhere as weather conditions permit, except 
in western Idaho, where the weevil population is very low. The weevil appar- 
ently overwintered successfully in the infested area in California, the heaviest 
infestations being around Pleasanton, where, by the middle of May, from 300 to 
800 weevils could be taken with 100 sweeps of the net. After the second 
cutting of the crop, populations were very low. Late in July the populations 
were greatest around Niles. Eut little damage was done throughout the infested 
area in California this year. 

GREEN BUG 

The green bug ( Toxorjtera grami num Rond.) appeared in injurious numbers on 
winter wheat in south-central Nebraska and southeastern Missouri following the 
very dry, warm weather during October and November. In the vicinity of 
Hastings, Adams County, Nebr. , several fields were heavily infested.

CODLING MOTH 

Although very heavy populations of larvae of the codling moth 
(Carpocapsa -pomonella L.) went into the winter of 1932-33, severe subzero 
temperatures in the East Central States produced very heavy winter mortality. 
In northeastern Kansas and western New York survival was high, as was also the 
case in the Pacific Northwest. The spring season was very much delayed, how- 
ever, in the Pacific Northwest, and in general but little damage was done in 
that region. Because of neglect of about 5 percent of the orchards in this 
region, however, a very heavy population of worms has built up, probably the 
heaviest ever recorded in the Pacific Northwest. Despite the setback received 
in the East Central States severe first-brood injury was reported from that 
region late in May and early in June, with similar heavy infestations in New 
England and western New York, westward through Michigan to Wisconsin and Iowa, 
and southward to Kansas and Tennessee. Later in the season second-brood and 
third-brood injury was reported from western South Carolina northward to 
western New York, and westward to Minnesota and Kansas, The only eastern State 
reporting low populations and slight damage was Delaware. In the East Central 
States Illinois reported the worst infestation in the last 20 years. Large 
numbers of larvae went into hibernation throughout the Eastern States. 

ORIENTAL PRUIT MOTH 

The first adults of the oriental fruit moth (Grapholitha molesta Busck) 
to be observed were seen in Georgia on March 12. They were next observed in 
South Carolina on March 24, in Tennessee March 31, and in Delaware April 18. 
The insect seemed to be more troublesome than usual in parts of North Carolina 
and South Carolina, Mississippi, Arkansas, West Virginia, and Pennsylvania, 
and considerable fruit injury to quince was observed along the lake shores of 
Ohio and New York. Considerable fruit injury was reported throughout New 
England and the Middle Atlantic States, westward into Ohio and Indiana. Infes- 
tations over the remainder of the country were light to moderate; there was 
practically no damage in the Port Valley, Ga. , peach section. No material 
spread was recorded during the year. 

SAN JOSE SCALE 

The winter of 1932-33 was very adverse to survival of the San Jose scale 
( Aspidiotus perniciosus Comst.) in the East Central and the North Central 
States. Illinois reported 90 percent mortality, Missouri £6 percent, and 
Wisconsin 94 percent in Sheboygan County and from 80 to 90 percent in Racine 
County. In the South Atlantic States Georgia reported 92 percent mortality 
following the freezing weather in February, and in the Pacific Northwest 
Oregon reported 40 percent mortality. As the season advanced a decided in- 
crease in the population was noted in Massachusetts, Georgia, Illinois, and 
Oregon. In Georgia infestations were more severe than they have been during 
the last five years, and encrusted trees were found in practically all 
orchards in Upson and Peach Counties despite the high percentage of winter 
killing. 






-332- 

PLUM CURCULIO 

The plum curculio (Co notrachelus nenuphar Host.) left hibernation quarters 
throughout the Eastern States at about the normal time. In the South Atlantic 
and southern East Central States winter mortality was very high; and early in 
the season larvae were very scarce. In the northern East Central and Middle 
Atlantic States, particularly in New Jersey and the Hudson River Valley of 
New York, damage was quite severe early in the season. First-generation 
beetles started to emerge near the normal date in the South. In Georgia the 
first adults appeared on May 27, 20 days earlier than last year, and in 
Tennessee on June 13, 8 days earlier than last year, which was a late year. 
However, the hot, dry weather prolonged emergence and then prevented oviposit ion 
by the few beetles that did come out; and the peach crop was harvested before 
any damage was done. Late in June and in July this insect was reported as very 
much more abundant than usual in the North Central States, particularly in 
Michigan and Wisconsin. 

FRUIT APHIDS 

Aphids attacking deciduous fruit were generally scarce throughout the 
Eastern States. Late in May, however, the rosy apple aphid ( Anuraphis roseus 
Baker) developed to troublesome numbers in New York and Virginia, and early 
in June this species was more or less troublesome throughout the Middle 
Atlantic and South Central States. 

SUGARCANE BORER 

The survival of the sugarcane borer ( Diatraea saccharalis Fab.) was 
unusually light in Louisiana and Mississippi following the severe cold weather 
of early February; and the larvae were scarce during the early summer. Late 
in August, however, the insect apparently increased rapidly. Several reports 
of severe damage in the Everglades of Florida were received. 

BOLL WEEVIL 4 

Because of the severe winter of 1932-33 few boll weevils ( Anthonomus 
grandis Boh.) survived in Oklahoma, Arkansas, and northern Texas. In Louisiana 
weevils were so very abundant in the fall of 1932 that, in spite of the fact 
that less than one fourth of 1 percent survived, they were about as abundant 
in the spring of 1933 as in the previous spring and considerably above the 
average. The survival was higher east of the Mississippi River and much 
higher than normal in the Atlantic States. Hot, dry weather in June and July 
greatly reduced the population in most of the States. This year's infestation 
was characterized by much local variation or "spottiness" caused chiefly by 
localized rains. The greatest damage in 1933 apparently was in Louisiana, 
Mississippi, and Oklahoma. Taking 'all of the infested States into consider^, id 
ation, the loss from the boll weevil was less than in 1932 but probably greater

-333- 



than in 1930 and 1931. At present weevils are about as abundant as 
they were a year ago. In some areas where leaf worms ( Alabama 
argil lac e a Hbn.) have defoliated practically all of the cotton the 
rfumber of weevils going into hibernation will be greatly reduced. 
On the other hand, in some areas the weevil population is building 
up rapidly this fall on cotton that is sprouting from the stalks 
plowed under during the summer in the cotton-acreage reduction 
campaign. This cotton is putting on squares in which weevils are 
developing in large numbers. 

PINK BOLL'MLM 5 

The pink boll worm ( Pectinophora gossypiella Saund.) did not 
appear during 1933 in the counties in northern Florida in which the 
insect was found last season. One dead specimen was found, however, 
in gin trash in Madison County, Florida, on September 22, at some 
distance from the counties found infested the previous year. 
Progress is being made in the suppression of the outbreak on wild 
cotton on the keys and in the southern part of the State. Two 
fields were found infested in Berrien County, Georgia, in the late 
fall. In the Southwestern States the season was particularly 
notable from the continued failure to find any trace of the pink 
boll worm in the Salt River Valley of Arizona, and that valley 
was removed from the quarantined area, effective September 23.. 
Several findings in the Stalled Plains region of New Mexico and Texas, 
however, made it necessary to add Lea and Roosevelt Counties, New 
Mexico, all of Cochran, Hockley, Terry, and Yoakum Counties in Texas, 
and parts of Bailey, Lamb, and Dawson Counties in the same State, 
to the regulated areas. In some of these counties the insect was 
found in the fields, while in other cases it was discovered in gins 
in gin trash coming from cotton grown within the counties concerned.

MEXICAN BEAN BEETLE 



Generally speaking, the Mexican "bean "beetle ( Epilachna corrupta Mais.) 
caused severe losses to bean growers in the Eastern and Southeastern States 
during 1933. Survival over winter was high, and damage would have been more 
severe but for a prolonged drought in several States. Beans were severely 
injured, and in many cases destroyed, in New Jersey and Delaware. Injury 
was severe in parts of Pennsylvania, Maryland, Virginia (western counties and 
eastern shore), North Carolina, South Carolina, Tennessee, Alabama, north- 
eastern Mississippi, Kentucky, and the Ohio River Valley in Ohio and Indiana. 
In some sections of the Ohio River Valley and also in eastern Tennessee, 
damage was lighter than usual. It will be recalled that this insect was first 
recorded in eastern Illinois last year. Infestation in that district was much 
lighter this year. The beetle was recorded, however, in seven additional 
counties in the southern part of the State, from Richland and Jefferson Counties 
to Massac and Union Counties. This year it occasioned considerable damage in 
southern Indiana. During July larvae were collected in the St. Paul -Minneapolis 
district of Minnesota, which is far northwest of its known distribution. This 
is believed to have been a commercial jump. This year it was found at 
Monticello, Fla. , and in southern Mississippi. Although the insect was ap- 
parently introduced into no rth^o enteral Alabama in about 1919, this is the 
first year that there has been any appreciable spread southward. 

COLORADO POTATO BEETLE 

Early in the season the Colorado potato beetle ( Leptinotarsa decemlineata 
Say) was collected in Lake and Pasco Counties, Fla., which is south of the 
previous records in this State. It was unusually abundant in the northern 
and eastern parts of Wisconsin and across Minnesota into North Dakota during 
July. Conditions over most of the country were about normal. In Utah 
beetles were found in three localities along the Weber and Davis County line. 
In the Yakima Valley of Washington they were much more troublesome than usual. 

VEGETABLE WEEVIL 

Throughout the winter of 1932-33 the vegetable weevil ( Listroderes 
obliqiius G-yll.) occasioned considerable damage to turnip and mustard; late 
in the winter it was recorded as attacking cabbage, spinach, and carrots over 
the southern two thirds of Mississippi and throughout Louisiana. About the 
middle of March this insect was found at Clemson College, S. C \ . This is the 
first record in that State and the northeasternmost record for the distribution 
of the species. 

PICKLE WORM 

The pickle worm ( Diaphania nitidalis St oil) was unusually abundant in 
Alabama and Florida.; many fields of cucumber, particularly those planted late, 
were completely wiped out in Florida, and 50 percent of the crop in Baldwin 
County, Ala., was rejected at the packing house. There was also considerable 
damage to summer squash. As the season advanced reports of damage were 
received from Mississippi, Kentucky, and Missouri. This year the insect did 
not persist in the northern part of its known range, where it had been trouble- 
some during the two previous years. 






. 



-335- 



TOMATO PIN WORM 



The tomato pin worm (G norimo schema lycopersicella Eusck) appeared again 
in troublesome numbers in northeastern Pennsylvania, where it not only in- 
fested greenhouse tomatoes but heavily infested numerous outdoor plantings 
near greenhouses. It was collected on tomatoes in a greenhouse in Norfolk, 
Va., in April. This is the first record of the insect in that State. In 
Florida, where it was first reported during 1932, it reappeared late in the 
season of 1933 "but not nearly as seriously as the previous year. ■ 

HARLEQUIN BUG 

The harlequin bug ( Murgantia histrionica Kahn) evidently suffered heavy 
winter mortality along the Atlantic seaboard, as populations were generally 
light throughout that region. Very early in the season it was unusually 
abundant in the East Central States, particularly from southern Ohio and 
southern Indiana to central and eastern Tennessee, Later, however, it 
appeared to decrease in numbers and was not so serious as was originally 
anticipated. 

FALSE CHINCH BUG 

During June the false chinch bug ( Nysius ericae Schill.) was reported 
from the West Central States through the Rocky Mountain region to the 
Pacific Coast, reports having been received from Minnesota, Iowa, Nebraska, 
Kansas, Colorado, Utah, Nevada, and California. Its principal damage was 
to cruciferous vegetables, though it was also reported as attacking straw- 
berry, potato, tomato, and flax. It was also reported as damaging orchards 
and vineyards. In California the outbreak extended from the upper 
Sacramento Valley to San Diego. This insect occurred in such enormous 
numbers at Wells, Nev., that it invaded the theatres, which had to be closed 
until the migration ended. 

PEA APHID 

During May heavy infestations of alfalfa by the pea aphid ( Illinoia 
pisi Kalt.) were recorded in New Jersey, Maryland, Kentucky, Missouri, and 
Kansas. In Maryland the outbreak was reduced to negligible proportions by 
a fungous disease. In Mississippi the insect was reported as attacking 
Austrian winter peas and English peas. In June it appeared in the cannery 
peas in Michigan. 

POTATO LEAFHOPPER 

Late in June the potato leafhopper ( Empoasca fabae Harr.) became very 
abundant in the Norfolk trucking section of Virginia. Reports of similar 
abundance were received from Ohio and Iowa. During July the insect and its 
associated hopperburn were reported as abundant and destructive from southern 
New England, through the Middle Atlantic States westward to Illinois and 
Minnesota, 'in the western part of that area dry weather, associated with 
the hopperburn, produced severe losses. 



-336- 
PERIODICAL CICADA 

Brood XIX of the periodical cicada ( Magicicada septendeciro tredecim 
Riley), the largest of the 13-year "broods-, appeared in great numbers through- 
out the greater part of its range. Two records from southeastern Kansas 
filled in a gap in the western limit of this brood. Three records from 
eastern Kentucky apparently extended the limits somewhat north of the 
previously known range. The interpretation of these, however, is confused 
by the problematical Brood, VII of the 17-year race. Brood VII, a small 
compact brood in the Finger Lakes district of New York, was due to appear 
this year. There are a few scattered records of a single year's appearance 
-'of this brood in western Pennsylvania and southern West Virginia. The 
Finger Lakes records have been repeated over a period of 136 years, but, 
strange to say, no records were made this year, although the brood was re- 
ported from seven counties in 1916. The insect was reported from two 
counties in the south-central part of Pennsylvania., "No previous records 
for this brood have been made from this part of the State; and the individuals 
were probably retarded or accelerated specimens of another brood, as are. 
possibly those of the previous records of this "brood "beyond the western New 
York State area. This year brood XIX appeared in the following States and

GIPSY MOTH AND BROWN-TAIL MOTH 6 

The first egg clusters of the gypsy moth ( Porthetria dispar L.) 
observed hatching in New England were seen on May 3. Dates of first hatch 
varied somewhat with the locality, the latest "being May 19 for one of the 
northern points. With the exception of some of the northern localities, 
hatching was general "by May 15 and maximum hatch came a few days later. 
In the Barrier Zone 32 infestations were found with an aggregate of 1,497 
egg clusters. Seventeen of these infestations were found in Massachusetts, 
thirteen in Connecticut, and two in New York, During the year the total 
number of acres in which there was partial to complete defoliation was 
397,000, as compared with 286,000 in 1932. In New Jersey a single scattered 
infestation of 112 egg clusters was found in an especially rough section 
about 6 miles northwest of Morristown. Intensive scouting and thorough 
treatment of egg clusters were followed "by spraying in June. All work was 
performed "by the New Jersey Department of Agriculture. In Pennsylvania the 
area of known infestation was found to cover about 230 square miles. The 
exact extent was not found, as hatching forced the discontinuance of scouting, 
This area, centering near Pittston in Luzerne County, embraced parts or all 
of 15 towns in Lackawanna and Luzerne Counties. Intensive scouting and clean- 
up work are "being continued. During the year, outside the "brown-tail moth 
( Nygmia phaeorrhoea Don.) quarantine line, 20 towns were found infested in 
Maine, 18 in New Hampshire, and 5 in Vermont. Much of the southern half of 
New Hampshire, and a corresponding area in Maine, was densely infested and 
heavy defoliation resulted. Furthermore, the hibernating webs were extremely 
abundant in this area late in the fall. In Massachusetts the infestation was 
generally light, "but here and there towns were found with areas of heavier 
infestation. 

SATIN MOTH 6 

North of the quarantine line, in Maine the towns of Crystal, Houlton, 
Molunkus, Reed Plantation, Silver Ridge, Staceyville, and Strong, and in 
New Hampshire the tov/n of Haverhill, were found infested with the satin 
moth ( Stilpnotia salicis L.). Within the infested area, severe defoliation 
was recorded in Bangor and Brewer, Me.; Alton, Ashland, Campton, Center 
Harbor, Freedom, and Laconia, N. H. ; and in Yariaouth, Mass. Elsewhere in 
the infested area the defoliation was not severe, though there was noticeable 
feeding in many towns.

JAPANESE BEETLE 7 



The range of the Japanese "beetle ( Popillia japonica Newm.) consists 
of two quite distinct suTd divisions: One, the area of continuous infestation 
which the beetle has come to occupy as a result of its natural spread from 
the original point of introduction; the other, the area of discontinuous or 
localized infestation which resulted primarily through artificial means of 
transportation, with the consequent establishment of colonies isolated from 
each other and from the main body of population. The former area is largely 
confined to portions of New Jersey, Pennsylvania, and Delaware, with minor 
protrusions into adjoining sections of Maryland and New York. The area of 
discontinuous infestation has been extended as far north as Waterville, Me., 
loodsville, N. H. , Burlington, Vt., Watertown, N. Y., westward to Detroit, 
Mich., and Columbus, Ohio, and southward through Princeton, W. Va., and 
Asheville, N. C, to Florence and Greenville, S. C. A still more southern 
limit was reached in the latter State at Charleston, where four beetles were 
taken in 1931, but where none has been taken since, despite the fact that 
efforts to trap them there have been made each year. Owing probably to the 
general reduction of beetle population during 1933, many parts of the area 
of continuous infestation show only a slight advance beyond the limits 
reached in 1932. This was particularly true toward the north. The area of 
continuous infestation for the first time penetrated into Maryland. Probably 
the most striking expansion of this area was that which took place in 
Delaware. The most impressive feature of the infestation in 1933 was the 
great reduction in the beetle population in the section that has been longer 
infested compared with the number present in 1932. 

ASIATIC BEETLE'S % 

There is almost no change in the known distribution of the Asiatic 
beetle ( Anomala orientalis Waterh.), and, aside from the record of collections 
of the Asiatic garden beetle ( Autoserica castanea Arrow) in Aiken, S. C, 
nothing of great importance has been found in the distribution of this 
beetle. 

ELM LEAP BEETLE 

In scattered localities in New England, the Middle Atlantic States, and 
East Central States the elm leaf beetle ( Gale rue el la xanthome laena Schr.) was 
very abundant. At one place in Virginia the larvae were badly infected with 
a fungous disease and their dead bodies around the bases of trees were so 
numerous that the odor was offensive. Spraying for the control of this pest 
in the larger towns and cities was quite generally practiced. We also re- 
ceived a report of heavy defoliation in the. Yakima Valley of Washington and 
the Yosemite Valley of California. 

BAEK BEETLES 

An epidemic of the western pine beetle ( Dendroc tonus brevicomis Lee), 
which has been very destructive since 1917, is now definitely on the wane 
in some localities. The number of trees killed in 1933 was from 50 to 90

percent less than those killed in 1932. This drop in population was "believed 
to. "be the result of the very, severe winter temperatures of 1^32-33. The 
.outbreak of the mountain pine "beetle (D. monticolae Hopk.) in the Beaverhead 
National Forest of Montana has been increasing since 1926, unfcil last year 
(1932) it covered over 1,000,000 acres of forest, and 17,500,000 trees had 
been killed. Following the very severe winter temperatures of 1932-33, the 
"beetle population in the Beaverhead and adjacent forests was reduced to such 
an extent that in 1933 the number killed was "but 5 percent of the number 
killed in 1932. There was no "beetle survival above the snow line in this 
region. In the Sierra Forest of California conditions are also very favorable, 
the beetle population "being the lowest since 1923. 

GLADIOLUS THEIPS 

.During the year the gladiolus thrips ( Taeniothrips gladioli M. & S.) 
continued to be reported as a serious pest of gladiolus. In addition to the 
territory already known to "be infested, it was reported for the first time 
in the vicinity of Milwaukee, Wis., at several points throughout Iowa, in 
which State a few specimens were collected in 1932, in Eddy County, N. Dak., 
and at Fort Collins, Colo. 

SCEEW WORM 

Late in the season a severe outbreak of the screw worm ( Cochliomyia 
macellaria Fab.) occurred in northern Florida and southern Georgia, where 
horses, cattle, and dogs were attacked. The infestation covered 30 counties 
in southern Georgia from the Alabama-Georgia State line to the coast, and 
12 counties in northern Florida. Infestations were found on deer, sheep, 
goats, cats, and even man, in addition to those on the above-named hosts. 
Losses were heavy both in dead animals and in the cost of medication. This 
is theafirst record of a serious infestation in the Southeastern States. An 
outbreak/in southern Mississippi, where the principal injury was occasioned 
to sheep. During September the number of cases of injury in southe-ra ^and 
Southwestern Texas doubled. In the Gulf Coast district of Texas stockmen 
reported that 35 percent of the cattle were infested. The outbreaks from 
Florida to Texas were closely associated with excessive rainfall and high 
temperatures during August and early 3.n September. 

NEW AND LITTLE KNOWN PESTS 

Otiorhynchus l^gustici L. is a well known weevil that attacks a wide 
variety of plants throughout Europe and the Near East. The larvae feed on 
roots and the adults feed on buds and leaves. In Europe it is known to feed 
on alfalfa, turnip, asparagus, clover, sugar beet, grape, peach, and straw- 
berry. It was first recorded in North America in 1933, when specimens were 
collected on newly-set raspberry at Oswego, N. Y. 

Sitona cylindricollis Fab. is a European weevil known to attack sweet- 
clover. It was first recorded on this continent in 1933 at Middlebury, Vt . , 
where it so severely injured young sweetclover as to necessitate replanting. 
It was also found on the New York side of the Lake Champ lain valley, and at 
Stoors, Conn., and Amherst, Mass. 



-340- 

Platynota stultana Wals., a tortricid leaf tier, was described (Trans. 
Ent. Soc. Lond., p. 127-8, 1884) from Sonora, Mexico. It has also been known 
in southern California for several years. In 1933 it was found damaging 
the new growth on about 15 percent of the 100,000 rose plants in a greenhouse 
in Alexandria, Va. In Mexico and California it is recorded as attacking 
cherimoya, red pepper, bell pepper, grapefruit, orange, cotton, walnut, 
avocado, and several other plants. 

Ptinus tectus Boieldieu, a beetle, described from Tasmania (Ann. Soc. 
Ent. France IV, p. 652, 1856), is widely distributed in Europe, where it 
attacks stored articles, including dried milk, cereals, chocolate, pepper, 
fish meal, fertilizer, and woolen carpets. The first record on this continent 
was made in the winter of 1S31-32 at Vancouver, B. C, and later that year it 
was found in stored fish meal in California and in imported' fertilizer in 
Washington. 



SUMMARY OF INSECT CONDITIONS IN HAWAII FOE 1933 
0. H. Swezey 

There were no outbreaks of the sugarcane leafhopper, Perkinsiella 
saccharic Ida. Kirk., of any consequence. This insect is controlled by its 
most important natural enemy, the Fijiian bug Cyrtorhinus mundulus (Bredd.), 
which sucks the eggs. 

Rhabdocnemis ob scura (Boisd.) is generally well controlled by the New 
Guinea tachinid Ceromasia sphenophori Vill . In particular locations, and 
with some varieties of cane, there is appreciable damage. 

The Asiatic beetle, Anomala orientalis Waterh. , continued prevalent in 
a particular area of one of the large sugar plantations, but the ac tus3u damage 
to the cane by its grubs was evidently slight, as the plantation produced a 
record crop. 

The Chinese rose beetle, Adore tus sinicu s Burm., continues as prevalent 
as ever as a garden pest. During tne summer over 2,000 adults of the 
parasite Tiphia lucida Ashra. were liberated in favorable places. 

The pink sugarcane mealybug, Trionymus sac char i (Ckll.), is now well 
controlled by the Philippine parasite Anagyrus saccharicola Timb., introduced 
in 1930. 

The pineapple mealybug, Pseudococcus brevipes (Ckll.), is becoming of 
less importance in pineapple fields as better spraying methods and field 
practices for control are being made use of. This mealybug is apparently 
increasing in cane fields. 

The Chinese grasshopper, Cxya chinensis Thunb., was less prevalent in 
some of the sections, where it was attacking sugarcane. The egg parasite 
Scelio pembertoni Timb., introduced from the Malay States in 1930, has been 
recovered in a few places. 









She corn ear worm, Keliothis o"br.oleta Fab., was very injurious to 
green corn, hardly an ear escaping injury. 

The Mediterranean fruit fly, Cer atitis capitata Wied. , continues as 
the worst fruit pest. Mangoes were considerably attacked. 

The mango weevil, Crypt orhynchu s mangiferae Fab., was found in about 
half of the mango seeds during the first half of the summer, but in only 
about one third of the seeds in the latter part of the season. 

The pepper weevil, Anthonomus eugenii Cano, was found for the first 
time in a Honolulu garden in February 1933. Since then it has been found 
widely spread on the island of Oahu, and was taken once on one of the 
other islands. Besides infesting the various garden peppers, this weevil 
is also infesting the fruits of eggplant and the common nightshade weed, 
5 Planum nigrum . 

The gladiolus thrips, Taeniothrips gladioli M. & S., has greatly in- 
terfered with the growing of gladiolus. Some gardeners have entirely 
abandoned growing it. 

Hemichionas-pis minor (Mask.) continues to make inroads on hibiscus 
hedges. If it is not taken care of when found it eventually kills the bush 
and spreads along the hedge. 

Orthezia insignis Dougl. attacks many kinds of ornamental plants and 
continues its destructive work on lantana in various parts of the islands 
where lantana is a pest plant, not e Jfcrys Idling it outright, but injuring 
it and checking seed production. 

An immigrant mirid bug, . Pycnoderes quadrimaculatus Guerin, which was 
first found in Hawaii in 1929, has this year been reported as quite injurious 
to string beans. 

The koa moth, Argyroploce illepi da "Butl., which usually is so destructive 
to the seeds of the endemic koa tree ( Acacia koa ) , destroyed only from 25 to 
60 percent of the seeds. The larvae have been quite common on macadamia njits, 
the injury being done chiefly in the husk. The seeds of a native tree 
( Alectryon macrococcus ) were found badly infested. 

The coconut leaf roller, Omiodes blackburni Butl., which has not done 
conspicuous damage to coconut leaves in Honolulu in the past 5 or 6 years, 
attacked the young trees badly this summer in a section of the city, giving 
the trees a very ragged appearance. This outbreak finally subsided, and 
examination sho7/ed an abundance of cocoons of the parasite Cremastus hyraeniae 
Tier., equivalent to a parasitization of 82 percent. Several other parasites 
had also been a factor. . 

The rice borer, Chilo simplex Butl., has not been so serious, the last 
ripening crop appearing to be about normal. On account of the ravages of this 
pest when it first made its appearance, there was considerable reduction in 
the acreage of rice, and much of the land has been utilized for growing truck 
crops instead. 

The subterranean termite Coptotermes formosanus Shiraki continues to be 
very destructive to wooden structures in Honolulu.
